    DOGE 10 MK2 is sold-out and discontinued

    It is now replaced by Doge 10 MK3 which will be assembled in early August to do massive delays in the supply chain after the covid outbreak in Guangzhou (Canton) where several of our suppliers are located.



    DOGE 10 is an awesome KT88 push-pull delivering 60W RMS. Doge 10 is unique as although 100% tube amp, it has the advantages of the solid-state amps + the benefits of the tube world (Thomas&Stereo).

     “Best bang for the bucks” (Thomas & Stereo). Watch the review below.

    Our customers who already own this amplifier gave us so much positive feedbacks and comparison with other brands they previously owned, that we consider it regarding customer’s reviews, as one of the best-integrated tube amplifiers on the market for its price. You might find some KT88 amps from China at $1099, sometimes even $899 without remote, sometimes with a pretty good appearance,… but none will offer such sound performance, so many features, and last but not least, such reliability as Doge 10. Our Doge 10 compares favorably with amps in the range of $3000 to $6000. 

    Please note that from 2014 to 2019 we sold under the model name ‘Doge PD88’. So you might find reviews on forums or blogs under that name.

    The main difference between Doge 10 & Doge 10 MK2 is explained at the bottom of this page. After Thomas & Stereo review who said that Doge 10 was awesome, but would target only 30% of the audience, we slightly modified the feedback loop to make it more versatile and we now think it will suit 90% of you. Thomas & Stereo has made in between some update having replicated on his sample unit the MK2 mods.

    Even Thomas himself didn’t make a full review of the updated version, one of his partners made one in which he is really enthusiastic about the MK2 version, please watch their videos.

    Please note that there is no difference in sound performance between this MK2 version and the new MK3 version, only Subwoofer & Home Theather features will be added to MK3 version. We can add Subwoofer output on this MK2 version instead of the Line-out RCA.


    DOGE 10 deserves the best speakers…

    With respect for our competitors, we don’t quote the name of the amps below as it exceeds their performance.

    Because our price is not only because we price more fairly than our competitors, it is also because of our system of direct distribution to you. Our competitors have to give profit margin to their distributors who promote them in exhibitions and visit regularly the retailers and of course to retailers who need profit margin to buy demo units.


    We recommend you to match Doge 10 with Doge 7 who got the Best 2020 DAC award!!

    The Doge 7 coupled with a tube amp has something unrealistic, magical…


    Doge 10 come with awesome comprehensive features

    • Doge PAB (Precision Auto-Bias) a computer-manager autobias
    • Doge DUAL CLASS mode, a computer-managed feature to switch from class AB to true Class A
    • Doge FLS (Feedback Loop Selector) for better speaker matching
    • Doge APM (Auto Protection Mode) to shutdown automatically the amp and protect your speakers if something wrong happens inside the amp.
    • Doge DTI (Dead Tube Indicator)
    • A sophisticated Soft-Start
    • A Ground Noise Reduction switch
    • A comprehensive remote in an elegant single piece aluminum
    • Turn-on/turn-off function from the remote controller. Very convenient

    Doge 10 is a KT88 push-pull integrated amplifier. it can be used with 6550 as well. However, it can’t use the KT150, and KT170 tubes. It can use the KT120 from Shuguang or Psvane but the Russian KT120s from Tungsol have an extremely high rate of defective tubes with unstable impedance and most of Tungsol KT120 will be recognized as defective by our DTI, so our processor will block them to preserve the safety of Doge 10.

    It can deliver 60 Watts RMS per channel in class AB and it goes to 30W in class A. Most of you probably know that true class A has less efficiency in counterpart it improves the sound performance.

    To sum up, the Doge 10 design concept, is we wanted to put the best of our technology and put in the best components, most of them imported. First of all, the key component is a pair of very high standard output transformers with high range Z10 core steel. Definitely, you can’t have a high-end amp without premium-grade output transformers. For other components we use Nippon Chemicon electrolytic capacitors, Japanese potentiometer ALPS “blue velvet” matched at 1% precision, German OMRON gold plated relays,…  And last but not least, you would be surprised if you were comparing the signal cable we use and those of well-known brands. Our signal cable is a very expensive silver-PTFE with shielding. We put attention to any single detail, like shielding even the inputs board with the relays.


    In any amplifier, a key component is the coupling capacitor as the signal pass through it. On Doge 10 we use UK high-end audiophile-grade coupling capacitor Claritycaps ‘ESA’ model, which we use in our famous Doge 8 Clarity preamp. We have been so impressed by their sound performance that we installed them on all our products. As a reference among many, the Italian speakers brand Sonus Farber uses them for their crossover in their $25,000 speakers



    We are proud to have introduced on the tube amps market in 2014 a totally new technology, the “Dual Class mode”. This is an exclusive feature of DOGE. Believe it or not, you really can’t find anywhere else worldwide !! 😎

    After the launch in 2011 of our patented Doge PAB Autobias, our microprocessor is now able to manage different levels of voltage and anode current. With Doge 10, you will be able to choose between class A and class AB within the same amplifier. It is really like having two amplifiers in one, making it very versatile for different types of speakers and even music.

    What is really different with Doge DUAL CLASS mode, compared with what you can read on our competitors’ websites, is that our class A is not what others call “floating class A”, which says for example their amp is in class A between 0 to 10W and then class B from 10W to 50W, etc…

    Such descriptions are for marketing purposes because an amplifier is either in class A or not. Period. True class A must have a very high anode current going through the tubes, whether you are at minimum power or maximum power. That’s the reason in class A we have programmed our microprocessor to set the anode current at the high value of 80mA to deliver a true class A with only 0.06% distortion, which is extremely low and extremely rare for a tube amp. For reference, 95% of KT88 amps have anode current from 30mA to 55mA. To be able to supply this high current to the tubes, the PADC microprocessor changes the main power voltage and the anode current (in class AB we have 50mA which is already in the highest standards). This is a process that requires around 45 seconds. That’s the reason only Doge 10 can say it is at the same time true class A and class AB, because you can’t use both at the same time.

    To be more practical as ampers are not familiar to most of you, in class AB the KT88 tubes get a 520V anode voltage, whereas in class A the KT88 tubes get a 460V anode voltage because it couldn’t have at the same time a high voltage and high current, which is the reason the max power is limited at 30W in class A. But you will be probably very surprised how these 30W sound like higher power because its very holographic sound. 

    Now some of you might think “why not do class A only if class A is a must?” Well, it is not that simple. Because class A in a push-pull design will have less distortion it might sound slightly less warm and, depending on everyone’s ears or tastes, some will prefer this lower distortion sound as very pure and neutral and some will prefer class AB, very “tubish” style. For some orchestral performance or live performance, depending on tastes and systems, class AB might sound better. On voices, class A might sound better. Finally, depending on your style of music and personal taste you might like one class better and this class might not be the same for everyone, as everyone taste is different and you, only, can decide which one you prefer and you might sometimes be willing to change according to the style of music you listen.

    We really make our best to make Doge 10 be one of the most versatile tube amp ever made, as something you never saw before. We didn’t even want to give this PADC feature to LUA as it is really “our baby” and knowing you can see it only on Doge and if some of you might think we are the ones who clone our OEM partner designs, it is the evidence all amplifiers manufactured by Doge, either on Doge brand or LUA brand are designed by Doge only (though a few customizations asked by LUA).

    What about the reliability of using a microprocessor in a tube amp?

    Since we launched our first generation of Autobias in mid-2011, we have never had any break-down of our microprocessor, which is a very well-proven STT unit (ST Microelectronics-Thomson).

    If you want to take a break before going further into technical explanations, you can watch Doge 10 in one of our customer’s systems. We think interesting to show you this video as at least 5 customers reported to us an awesome match between Doge 10 and the Tekton speakers we have no idea technically why, but in case you need to buy new speakers as well, you can’t be wrong with matching Doge 10 with Tekton’s (and we have no commission on Tekton sales 🙂 )



    Any designer would have stopped here, but we still wanted more! So we created the FLS (Feedback Loop selector) function. Although you find now this feature and a few other brands (really just a few), we were among the firsts to do it if not the first. Almost all amplifiers have a negative feedback loop, which in two words means the amplifier re-inject a little part of the output signal into the input stage to make it more stable. In the 60’s this was considered as an improvement. But after some years have passed, many audiophiles consider the “zero feedback” as “the nirvana”, but this kind of electronic diagram requires ultra-stable speakers as it lowers the damping factor. Our point of view is we don’t know which speakers will be used with our Doge 10, so we preferred to do a design it with a feedback loop, but to let the user the choice of the strength of this feedback loop.

    We offer three choices, normal, medium, and low. Normal is what you find in most amplifiers on the market, whereas “low mode” is close to the zero feedback loop’s amps. This choice is to make upon your taste after listening, and “low” mode still keeps a little feedback to keep the amplifier stable and good damping factor.



    A good amplifier starts with a good power section.

    To supply the correct amount of power in particular in class A, we use a huge power transformer and a “Pi filtering” with a huge choke of 1H/1A.

    A “Pi” filtering is an association of an electrolytic capacitor, followed by a choke for filtering and a second electrolytic capacitor. On Doge 10 we have 500µF before and 500µF after the choke, so a total of 1,000µF !! It is an incredible source of energy. You will have in the same time a super silent power and firm and incredible basses even at Pmax 

    A big choke can have a cost similar to a transformer, in particular, if like us, you use premium Z10 core steel. That’s the reason many manufacturers in the low or medium range, don’t use choke or make it very small. To make an explanation by image, we have chosen the internal picture from the integrated of a brand worldwide famous at $3,590. You can see the difference in size and construction quality of their choke, no need to add other explanations. To avoid any scale trick we have circled the ALPS potentiometer as we share this same component to show we use the same scale on both photos. 

    Making this explanation we don’t intend do mean that amps without choke have bad sound (we don’t make secret we don’t use on our Doge 5 at $1K, for example, to make it more affordable), and that doesn’t mean either that amps with smaller choke have necessarily bad sound, but, we wanted to point out we really put very high quality and expensive components inside Doge 10 and its smart design combined with high range components both together make an incredible sound! it is also visible on the scale with 29Kg unpacked.



    Compared to our first generation of PAB Autobias from 2011, we have put all the tubes LEDs on the front panel in order to make that the tube sockets area doesn’t look like a “Christmas tree”, and instead, we put a nice anodized aluminum plate. So everything can be controlled from the front panel.

    We offer as an option (many of you want to see the tube), a sophisticated protection cage which holds with strong magnets (enough strength for kids’ hands) so the appearance is elegant no visible holes on the chassis and no screws on the grid.

    It has a very holographic sound stage, we could say a 3D sound stage. It’s ultra-low distortion rate makes that you can listen for hours without feeling tired. The basses are particularly firm and dynamic.



    We want to let you know that the Doge 10 has been tested in the German STEREO magazine under model name LUA Sinfonia at $6500. It got the mark of 92% and 4 stars for the price value. You might think, and that would make sense, that probably this model shares the same schematics with the Doge 10 but certainly, the German partner put higher range components in it?


    The LUA Sinfonia uses very reliable, but industrial, Wima coupling capacitors whereas our audiophiles grade UK Claritycaps are 10 times the price of the Wimas. You can also note the number of connectors required by Mr. Lua whereas our Doge 10 use soldering only for perfect conduction and avoid any loose contact. We want clearly claim our own brand DOGE products are higher standards than our OEM German products. And you can understand why Doge 10 is a true bargain compared to the 5900€ of the Sinfonia!



    With NOS tubes worth $2500 that you can buy by yourself for cheaper it was ranked 95%


    We are fully aware that considering the German price we could have priced Doge 10 at higher levels. We really first wanted you to enjoy it. It might be in coming months we slightly increase its price, but it will be no more than a few hundred dollars.



    With the success and feedback from “Thomas & Stereo” Youtube Channel, we have concluded in order to provide the best possible experience to our future clients and from an audience that Thomas described as “it will suit to an audience of 30% of you only”, we expect these customizations will make move Doge 10 to an audience which will be almost all of you.

    Then we have decided to offer 3 versions of the Doge 10.

    Doge 10 MK2-A: Exact version Thomas & Loic initially reviewed. Incredible airy sound stage with an emphasis on resolution.

    Doge 10 MK2-B: An increase in warmth and musicality. 90% soundstage compared to the original version. This version will be the default version unless you specify otherwise.

    Doge 10 MK2-C: Warm, emotional, and musical. Excellent for long listening sessions. 80% soundstage compared to the original version.

    In our opinion, MK2-B is the best balance of both worlds unless you have really bright speakers or you are looking for a very musical-sounding amp. If you want version A or C, please mark it in the “remarks” field at checkout.

    Please note that none of these versions are A or C are bad. They are all good. it all depends on your personal taste. Spoil yourself according to your own taste. So far we had 20% demand for A version, 60% demand for the B-version, and 20% demand for the C-version.



    Doge 10 is supplied with the following stock tubes:

    KT88: Psvane KT88-C. It can be moved with no price change to Shuguang 6550B (please see the picture), which would bring a bit more warmth.

    12AT7 and 12AX7: according to availability.

    If you want the 6550B, just at check-out put in the “comments” field: “please supply 6550B”. Please note with 6550B, Pmax will be limited to 55W. Because of its smaller glass, it has less heat dissipation.



    Due to shortage of tubes in Chinese factories, we don’t offer anymore tube upgrade until winter. You can choose without tubes and buy your own tubes from online shops like Tube amp doctor or others.

    10 reviews for DOGE 10 MK2-B

    1. HermieD (verified owner)

      I am absolutely happy with my Doge 10 Mk2-B – it is the best money I have spent on audio. This amp is very transparent and musical, and I find myself just enjoying my music more and listening longer. My journey looking for an amp ends here – this is all I need!

      Marc and the Doge team have been excellent to deal with, in spite of their sudden fame. The shipping was fast, and the amp was well protected.

      My first experience with the Doge 10 was during a two-week period at Christmas 2020. I live nearby Thomas, the Thomas and Stereo HiFi reviewer and he generously allows me to evaluate multiple pieces of HiFi gear each month. However, when I evaluated the Doge 10, I fell in love.

      It gracefully combines the smoothness, transparency, and holographic sound of a high-end tube amp, with power and dynamics of a solid state – the blend of both in one amp is an incredibly engaging experience. Thomas had lent me a set of Tube Onyx mono block amps for the month of March 2021 – I loved those mono blocks as well, the smooth sound was beautiful, but it lacked the deep snapping bass and dynamics I experienced with the Doge 10.

      I love the features of the amp, including the Class A, Class A/B setting and most of all the Feedback Mode selector that lets you fine tune the sound for your speakers – set at Low the sound with my Klipsch Forte III speakers is smooth, still precise, and holographic.

      After evaluating countless amps (including prior to meeting Thomas) no amplifier, tube of solid state has satisfied me to the point the Doge 10 does. That cold day in January when I returned the Doge 10 to Thomas, I immediately ordered my own, and now happy to have it sitting in my living-room.

      The Doge team, particularly Marc, have been very responsive, courteous, and kept me up to date on progress – the massive amount of interest in Doge has resulted in a wait time – but I can assure you it’s well worth the wait.

      Here’s a link to the guest review video that I did on the Thomas and Stereo YouTube channel:

      Hi Team Doge

      I probably now have over 80hrs running time on the Doge 10 MkII. Sound seems to have settled in nicely.

      Man, this integrated really is special. It just conveys the emotions in the music so easily. I mean when’s the last time you got goose bumps listening to music? Or almost tears in your eyes?

      With the Doge 10 it just keeps happening – time and again. Enough said!!



      just a quick note about the Doge 10 that i received a few weeks ago. Wanted to let you know what a pleasant surprise this amp has been. For this amount of money the build quality is amazing. The first thing I noticed was the complete lack of any hiss or any sound at all coming through the speakers when there was no music playing. I have a few other tube amps and that definitely isn’t true for any of them and actually that would include some solid state amps that I own as well. The second thing I wanted to let you know about was that though there are many things I prefer about the sound of tube amps over solid state, like that round, three dimensional character of the imaging for one, however, bass extension and tightness isn’t one of them. The Doge 10 though still doesn’t quite have the punch to my solar plexus like my other solid state (some class A B and a pair of class D mono blocks) amps do but, I was surprised at how much of that experience you do get from this amp. With some tube rolling I could probably get even closer though in terms of my daily listening I have felt like I was not missing out very much and what It does produce is very enjoyable. I still can’t get over how all this comes with a price tag that usually one would have to spend quite a lot more for. So I just wanted to share some of my initial impressions with you as I’m sure as their rep you would like to hear about. Now we’ll have to see about that DAC soon.

      The Doge 10 integrated tube amp delivers outstanding performance with a large spacious soundstage, precise imaging, and outstanding detail. I received the unit last week and have already listened to it for more than 40 hours. It came packaged very well and Marc was quick to respond with any questions I had. Everything worked out great. If you can be patient, it is well worth it.

      I have this paired with a Doge 7 DAC. The pairing seems to be very good. I bought Gold Lion KT88s and Tong-Sol 12AX7s and 12AT7s. I’m very happy with these tubes so far and I am looking forward to hearing what they will evolve top over the next 100 to 200 hours.

      I have put together a few videos if you are interested to hear more about my experience.

      Doge 10 Thoughts

      Doge 10 Sound Demo

    6. daniel griffiths

      It took 5 months but worth the wait, the buying process wasn’t easy as Doge was overwhelmed with orders. Mine is the MK2-B and compared to my IOTAVX SA3 it is lively and detailed but still well rounded. Admittedly the Iota is more entry level. Doge 10 paired well to my Acoustic Energy AE509 speakers, previously they sounded slightly reserved. The biggest surprise has been the bass, I did not expect the deep and powerful bass. This is even before the REL T7i is added with no problems on the high level input. Upgraded to the Telefunken smooth plates input stage valves/tubes but haven’t A/B tested against others. All in all very happy, the sound and quality are everything I expected, even after the hype. Quite an achievement.

    7. David Eng (verified owner)

      The doge 10 version b is an absolute gem, full body sound with amazing holographic sound stage, great craftsmanship on build. I have had technics, Fischer, kenwood , naim, McIntosh amps- this doge is easily the equal or superior to them. If you had to buy one , the Doge 10 should be your choice. Easy setup out of box, impeccable packaging for shipping. Plus Marc is a great contact person for any questions.

    8. Jeff Cummings

      I purchased the Doge 10 MKII late last year and I love it. It’s dynamic and the soundstage is great. I’m driving a pair of Fyne 500’s, and it’s been such a joy to have in our room. The combo is great as we don’t have to be sitting exactly in the sweet spot to enjoy it. The sound fills the room. It has plenty of power with speakers that aren’t super efficient. I’ve also tried out my KEF LS50 and Buchardt S400’s and they all sounded great with the Doge 10 (even though each has their own sound). I’ve done some tube rolling, but it’s not necessary in my opinion. I’ve been tempted to change the caps based on what Thomas & Stereo said, but honestly, I love how it sounds so I don’t really want to mess with a good thing. The only thing I would say is that I find myself going back and forth between class A and A/B and can’t decide which one I prefer. I know Doge got hammered with sales after the reviews from highly regarded YouTube channels like Thomas & Stereo and Next Big Thing, but once the dust settled, Marc was super responsive to all my various questions. If you’ve been buying audio as long as I have, you know how rare that is. The Doge 10 is going to be a permanent part of my audio setup for years to come. I’m already saving up for the Doge DAC.

      Highly recommended!

    9. bh9907160

      Unmistakably a great value that punches way above its price point. I would go as far as to say that this integrated amp sounds superior than many separates, which may require much trial and error between the pre amp, interconnects and amplifier to produce the liquidity and synergy that this unit offers. Like cooking, yes, most dishes from scratch taste more authentic than most ingredients out of freezers, cans and/or jars; however, that is, If and only if, the cook has mastered the art of combining the correct ratios of ingredients at the correct place and time for perfect integration. The painstaking process has been completed with excellent execution. 9.5/10

       Don’t think, just buy!!

    10. Juergen Neutz

      The Doge 10 is a phenomenal device. I have had several amplifiers, but the Doge 10 beats them all. I can fully support the review from Thomas & Stereo. I would go even further to say that at least 80% of people who buy the device will be more than happy with it. The build quality is stunning and even so the sound. Treble, mids and base are how they should be for a high end HiFi device. It packed really great so that a save delivery is assured.
      Well done Doge team!
      I will write further comment once the break-in period is over

    11. Joseph – Pennsylvania

      Hello Doge – this is NOT an review !
      I suggest you support your products – with offers of TUBES; that connector for Doge 8 & 9 – we all know cables DO fail in time. And any other item to assure this equipment will continue working in the future.
      What occurs to me and concerns me is the BIAS control board. How long will this last? Can you make this board available? Is there anything you can think of WE may need and is not available here is the United States?
      It seems 211 tubes are very hard to find. I found TWO stores trying to sell the Natural Sound tube for nearly $1000.00 an quad – No one will pay this price – they are dreaming! I know I can contact the company in Hunan – BUT I would place TRUST in DOGE assuring WE can get MATCHED quality tubes.
      Had my Wife talk to someone in China….surprised they do not believe matching is important. Had the same experience with an company selling Treasure tubes in Canada. This problem means WE can not get tubes!
      PreAmp tubes are not an problem, what is needed is: 6CA7 and 211 tubes.

      On a side note – I request an better explanation of the FEEDBACK control on the Doge 9: normal, med/mid and low. I have top of the line Definitive Technology speakers.

      Appreciate your time and hope you like the review. Sorry I looked like a slob when I did the video

      Found the Prima Donna Amp by following the YouTube video done by Oto. I was looking at the Tekton Design Impact Speakers (first Double Impact but my room is small so I didn’t need ‘that much speaker’. This Amp is an excellent match to to the TK Impact Speaker design- the sound stage is amazing, the Amp is so quiet during music pauses it’s almost unreal but the power is there if you want it. Combined with a decent turntable and the music comes alive. Shipping was easy with payment through PayPal. I had a few customer service questions and followed the links – responses were within hours. Overall very satisfied with the system and I’ve recommended this set up to several friends. Well done Doge!

      Hi Marc,

      I have received the Prima Donna, so far it works wonderfully !!!

      The auto bias is amazing!
      As well, all the other technologies implemented in the unit. Bringing tube technology into 2020 !

      The sound of the Prima Donna 88 is warm and precise. The Tekton Design – Double Impact speakers on Class A setting came alive and really unleashed the beauty of the sound these speakers are capable of producing. The Prima Donna with a nice DSD player and the Tekton Double Impact pair of speakers will sound like a high end system satisfying even the most demanding listener.
