    DOGE 10 is an awesome KT88 push-pull delivering 60W RMS.

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

     “After making videos for many years, my goal was always to find that gem” (Thomas’ sentence at 23’05” from Thomas & Stereo Youtube channel). You can watch the review below.

    “It is unique as although 100% tube amp, it has the advantages of the solid-state amps + the benefits of the tube world.” (Quote of Mark Scott in Thomas & Stereo third video with Mark S. as guest testing MK2 version https://youtu.be/YeG1IIV_Iq0)

    Our customers who already own this amplifier gave us so much positive feedbacks and comparisons 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 not to say THE BEST.

    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 $4000 to $8000. 

    We are so so happy with this MK3 version that we have discontinued the Doge 9 monoblocks as we thought they didn’t over-perform Doge 10 anymore and we wanted our flagship to go one step further. So we sincerely think it is the best amp designed by our company, included the German LUA models sold under OEM cooperation at prices up to $8,000 (retail, in brick and mortar German shops).

     

    The main differences between Doge 10 MK3 and previous versions:

    After the first review of Thomas & Stereo who was highly impressed by Doge 10 3D sound stage, but found Doge 10 warmth in between tubes and solid-states, we have totally revisited the negative feedback of Doge 10 to keep the same 3D stage but have further warmth and silkiness. The sound improvement is really significant and DOGE 10 MK3 will really make you cry of emotion on your favorite tracks which was the only thing Thomas regretted on MK1 version.

    In a third Video of Doge 10, (a Doge 10 MK1 modified into MK2), one of Thomas & Stereo buddies, Mark Scott, has been already impressed by the first warmth improvement. https://youtu.be/YeG1IIV_Iq0

    1) Improved sound performance, more warmth more emotion, some micro-details you will realize you have never heard before, AND a still incredibly huge 3D sound stage.

    2) Class A reaches now 40W.

    3) an LFE Subwoofer output mono & stereo, which requires an isolation system to avoid rejection of signal into the tubes. Whereas it is something very simple and current in the solid-state world. Most tube amplifiers on the market having subwoofer outputs are priced at least $3,599.

    4) Doge 10 MK3 has a “pre-in” input, in case for example you want to drive Doge 10 by the pre-out of your HT amplifier. Please don’t mistake HT bypass which is a feature only in the preamp and not on integrated. HT bypass doesn’t exist on integrated amps.

    5) Compared to the MK1 version, the MK3 is more musical, less solid-state colored (which was a bit too Chinese taste), warmer but without being caricatural tubish. The basses go even further.

    6) Doge 10 MK3 is offered in full black color OR in silver.

    7) Note: Why do we have many new features like PRE-IN or SUB-OUT and not XLR inputs???  Simple: 99% of the input stages of the tubes amplifier works in class A single-ended. So if we add an XLR input, that would mean we would have to unbalanced immediately it before we send it to the potentiometer. Be careful of all devices that have XLR.

    XLR input or output doesn’t mean neither “balanced unit” nor “fully balanced” unit. XLR is just a format of jack connector. XLR connections have interest only with fully balanced devices and 80% that you believe fully balanced are not.

    =========

    You can watch the 22mn review of Doge 10 by Thomas & Stereo below which is 10 months old,

    BUT, and it is important BUT:

    The video below is the review of the MK1 version and was already regarded as awesome. The MK3 is significantly improved.

    The review of Thomas & Stereo, for those who are followers of Youtube reviews, is nicknamed a “rave review”. That means Thomas fell in love with Doge 10 to make simple.  Here is the feedback let by Jurgen N. from Germany, which you can also read in the customers’ review section. He was one of the first Doge 10 MK1 owners and got the privilege to get a DG10 MK2 customized with the same schematic as MK3, so he is the first customer worldwide to have listened to the MK3 version:

    “After owning the Doge 10 MK1 version now for almost a year, I was able to upgrade to the newest MK3 version with the great support of Marc. Thank you for this. I can clearly say that it is a great sonic improvement with the MK3. The sound is more holographic, more detailed and smoother than compared to the MK1. But I could have lived with the MK1 version as well, because it is also great. At the end it is all a matter of taste and own preferences. The Doge 10 is truly high-end HiFi gear and it is hard to get better without spending a fortune. It is one of the best HiFi equipment if ever owned. Thank you so much Doge team!”

     

     

    Reviewers warned us not to compliments ourselves as we are not objective and let them do it. However, I, Marc, sales manager, having to distribute around 15 Chinese brands in my past job and being in China Hifi since now almost 15 years, I can say it is the best-integrated amp I have ever heard in this range of price. (I heard Japanese brands, US brands… I just have to admit to be fully transparent, that I never heard any integrated above $15K and this $15K was one of the most famous brands worldwide).

    It really gave me chills and have at the same time plenty of micro-details I never heard before and deep sound stage and sickness close as triodes. In a comparison video with Cayin CS55 and R8 (https://youtu.be/YeG1IIV_Iq0), Thomas said if you want to cry you should choose the Cayin or the R8. This remark pushed us to revise Doge 10 and make it finally the most emotional of the three, keeping the same highest 3D sound stage (we bought the R8 and the Cayin to compare the sound performance and design the MK3). So it is not just a “we are the best”, we listened to our competitors and we made DOGE MK3 the best.

    I can tell you and already warned Thomas who didn’t hear yet the MK3, to prepare packages of Kleenex, and let’s prepare yourself to cry listening to your most emotional tracks!!!

    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 and tone control
    • 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 controller made in a single piece of 18mm 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 unstable grid voltage with unstable impedance and many of Tungsol KT120 could be recognized as defective by our DTI, so our processor will block them to preserve the safety of Doge 10. If you use KT120, please source them from Tube Amp Doctor or Upscale Audio only.

    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.

    CLARITYCAPS

    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

     

    DUAL CLASS MODE

    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 on a tube amp !! 😎

    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 a very high value 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 25mA to 50mA. 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 510V 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 40W in class A. 

    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 performances or live performances, 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. Even in Doge team opinions are shared. Sales manager prefer class AB whereas designers prefer class A. So versatility is important. John Ford said in 1905 about his Ford T: “you can choose any color you wish since it’s black” and finally GM got the lead offering color choice.

    We really make our best to make Doge 10 be one of the most versatile tube amp ever designed, as something you never saw before. We didn’t even want to give this PADC feature to our German OEM ex-partner 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 cloned 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, mainly adding fuses everywhere).

    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 it 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 a good damping factor.

     

    THE POWER STAGE

    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 (CLC) is an association of an electrolytic capacitor, followed by a choke for filtering and a second electrolytic capacitor. On Doge 10 we have 235µF before and 500µF after the choke, so a total of 735µF !! It is an incredible source of energy. You will have at the same time a super silent power and firm and incredible basses even at Pmax. As far as we know it is highest value for KT88 push-pull in integrated below $10K.

    A big choke has 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 amp 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 supply a sophisticated protection cage that 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.

     

    WHAT ABOUT ITS VALUE?

    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?

    WRONG !

    The LUA Sinfonia uses very reliable (and sonically decent), 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. Our first goal was we really wanted you to be able to enjoy it even for audiophiles with moderate income. 

     

    TUBES POLICY

    Doge 10 is supplied with the following tubes:

    KT88: Psvane KT88-C. It is an incredible tube, one of the best on the market not to say the best. It has exactly the same internal architecture and components as KT88-TII except the gray coating on the glass which in our opinion is more marketing than scientific 🙂 

     

    UPGRADE OPTIONS

    We are pleased to announce that Doge 10 is now supplied automatically with upgraded tubes. Our historical partner Shuguang Tube factory is closed until spring 2022 so we inquired about new supplies and we made a partnership with the german brand TAD (Tube Amp Doctor) which is the biggest tube dealer worldwide and make his own brand of tubes which are in fact tubes manufactured by the main tube companies, but with very severe sorting done in TAD german Labs. Only the best 20% tubes are selected to become a “TAD Premium Selected” tubes.

    What makes a preamp tube become a TAD PREMIUM SELECTED?

    All preamp tubes labeled Premium Selected have passed the following tests:
    –      Low Noise Test
    –      Microphonic Test
    –      Gain Test
    –      Sonic Tests
    –      Shock Tests
    –      Listening Tests
    –      Balanced Output Test

    If you have already your own tubes or you want to choose other models you can order without tubes.

     

    THE SAFETY PACK OPTION

    We provide the warranty service in your country as it is easy to find some repair shops. However, we provide a tube warranty in China, which means you need to send back any potential defective tube during warranty time and pay the shipping cost for return. We don’t make a secret that in practical, except for those crazy of packing, it means almost no warranty.

    To avoid any frustration about potential failure, which is rare but can occur even a few days after the delivery, we offer a “safety pack option” that includes one spare part of each of the tubes. So if you chose this recommended option, as it can serve even outside the warranty period, you will get one extra KT88-C, one extra TAD Premium ECC81 & extra TAD Premium ECC83.

    It’s really up to you if you are lucky or unlucky (Remind Lucky Strike ad!).

     

    PRICE POLICY

    > Factory-direct price: once you will have checked out (without the need to register) you will fill your country and see our total price with includes delivery to your front door, Paypal or CC fees, and one year warranty served in your country. If you pay by bank transfer you will get 5% discount as our bank doesn’t charge us any fees (use coupon code “bank”). Possible taxes in your country are at your charge.

     

    Please note that for safety reasons according to international air freight regulations, remote controllers are not supplied with batteries. We use AA type batteries. Please plan to purchase some prior to the delivery.
