Description

If you are lazy to read the following description go to the footer and read directly the review of our first Doge 5 buyer, Mark S. from California  an experienced audiophile and already Doge 8 owner.

An astonishing 40W EL34 Push-Pull with the latest Doge technology the “PADC”, our patented Precision Autobias with Dual Class (A/AB). At just $1K it is a steal !

Some of you might remember Doge 5? We produced it from 2011 to 2017 and it was the first amplifier worldwide to get a “fix-autobias”. Our customers really loved it, but its external design was a little bit old style, so we discontinued it in 2018 due to lower demand.

Since that time, many of you asked us if we could use the EL34 tube on our Doge 10 integrated, showing us there is still a demand for EL34 aficionados, a tube slightly warmer than the EL34.

So we decided to redesign the DOGE 5 in a new chassis and new features, including the second generation of our PAB Autobias microprocessor that allows our exclusive Dual-Class mode management, with the choice of class A or class AB. That means you have really two amps in one, as the voltage and the anode current in class A and class AB are totally different, and believe it or not, Doge is the only manufacturer in the world doing that!

Different voltages mean different powers. Class A is more energy-consuming and has 30W whereas class AB has 40W. We improved the power section a bit and gained 5W compared to the previous DOGE 5 in class AB. To make it simple, class A has a higher anode current, but we need to reduce the voltage. This higher anode current makes the sound a bit “purer”. In class AB, the anode current is lower so the voltage is higher. The reset time to switch between two class is around 50 seconds as our microprocessor recalibrate voltage and bias as explained above.

Many of you might think “why not doing only class A if class A is better?” Well, it is not that simple. Because class A on a push-pull will have less distortion it might also sound slightly less warm if the ears of some of you. For some orchestral performance or live performance, depending on everyone’s tastes and systems, the class AB might be preferred by some of you. Finally, depending on your style of music and personal taste you might like one better and this one might not be the same for everyone. For the owners of Doge 10, that use this feature for several years now, some users use only class A, some only class AB and some switch of class from time to time.

The last point is Max power. Some speakers might be low efficiency and you might need the 40W of the class AB. So it is a very comprehensive amp, for all styles of music and systems.

  • Includes our exclusive PAB (Precision Auto Bias)
  • Includes our DUAL CLASS mode, a unique new feature to switch from a 100% Class A mode to a 100% class AB mode
  • Includes our APM (Auto Protection Mode)
  • Includes our new DTI (Dead Tube Indicator)
  • Includes a sophisticated Soft-Start
  • A comprehensive remote in an elegant single piece aluminum
  • Turn-on, turn-off function is on the remote controller. Very convenient

To sum-up Doge 5 PADC, is all about simplicity and clarity with up-to-date features and lastest Doge technologies. It uses very high-quality components, in particular high-class output transformer made with Z10 core steel imported from Japan (with 6% silicon) we also used this Z10 core steel for the power transformer, which allows us to offer real 40W RMS.

For those who know the Jolida brand or Jolida story (you can read in “About us”) Mr Liu our general manager took inspiration to design Doge 5 from the Jolida JD202 that designed in 1995 under the title of chief engineer. It keeps the sound color of the JD202 but goes much much further in terms of sound performance. In addition to higher range transformers, higher range capacitors he also improved the PCB layout using a double layers PCB to make the signal path shorter.

COMPONENTS IMPROVEMENTS

The electrolytic capacitors are Japanese Nippon-Chemicon and we moved on this latest version to the high-end coupling capacitor Claritycaps that we use in our famous Doge 8.

The new Doge 5 PADC comes with the same magic “PAB” (Precision Auto Bias) which is a fully microprocessor-controlled Bias and just needs to press a button on the front panel or the remote controller to set the bias instead of using a voltmeter and a screwdriver.  But compared to our previous Doge 5 using the first generation of autobias, we have put all the tubes LEDs on the front panel in order to make the tube sockets area not to look like a Christmas tree, and instead, we put a nice anodized aluminum plate. In case you make the bias check or bias reset from your sofa with the remote controller, it is more convenient to see all LEDs at the same place.

It has a warm gorgeous sound, a very neutral, beautiful voices, without lacking any bass. It is very musical and for people who never heard a tube amp before it will be a happiness shock.

If you compare it with more expensive amps, you will never believe it is just $1K !

We offer a protection grid as an option, a very sophisticated removable unit that holds with strong magnets (enough strength for a kid’s hand) so the appearance is beautiful with no visible holes on the chassis and no screws on the cage.

To let you understand, though very attractive price, Doge 5 is not low end amplifier, you can see on this video that is has the same size as Doge 10

 

NOW LET’S MAKE TALK MARK OUR FIRST CUSTOMER TO HAVE RECEIVED THE DOGE 5. MARK OFFERED TO BE A BETA TESTER. I WOULD NEVER IMAGINE HE WOULD MAKE SUCH A DETAILED REVIEW AS HE BOUGHT IT, IT WAS NOT A GIFT. Disclaimer: Mark paid his Doge 5 unit. He just got a very small discount by offering his help in doing a review. We never excepted such a detailed review!

HERE IT IS:

“Marc-

Many years ago I had pair of EL-34 based Dynaco monobloc amps.  I remembered their tone fondly, but sold them because their speaker strip was the old technology and it was challenging getting large, modern spade lugs to make contact directly.  I upgraded to an octet 6550 based amp which performed a little bit better on the low end while giving up some in the midrange. I had been looking for an EL-34 based amp and was close to buying a decades old Conrad Johnson. Buying a decades old vintage amp is a bit of a dice-roll, and I was hoping to get more recent technology.  That’s when I happened on the Doge 5 PADC. It was EL-34 based, used great caps and had auto-biasing built-in. I ordered the unit and awaited it’s delivery. I have used a Doge 8 preamp and a Doge 7 DAC for years so I was very familiar with Doge’s great build quality and musical performance.

I received my Doge 5 integrated amplifier a few weeks ago, unpacked it and immediately swapped in my preferred tubes: 2-GE 5751’s, 2-GE 6201’s and 4 matched KT-77 power tubes.  I let the amp burn-in for a week before I sat down for a serious listening session. My associated equipment: Benz Micro LPS, VPI TNT w/12.6 tonearm, Aesthetix IO Signature phono amp, Von Schweikert VR-4 Sr mk lll speakers and solid silver cables all around. Let me dispense with any suspense, this is a great little amp, but for $1,000, this is a STEAL. Over the years I have come to believe two things about stereo systems: 1) It is all about system synergy and 2) there are a lot of compromises and trade-offs.  My regular (speciality) amp is an 845 SET amp ($6k) list.  In my opinion, for acoustic and simple vocals, I haven’t found anything that can touch it.  However, it lacks heft and weight on complex and dynamic passages (hence speciality only for acoustic music) and this is where the Doge 5 really shines.  EL-34 designs do a great job with vocals and the mid-range in general and the Doge 5 is no exception.  Although not quite the equal of the 6 times more expensive SET amp in the mids and highs, it is pretty close.  But the kicker is that it brings the meat-on-the-bone and delivers a wonderfully organic sound across the spectrum, besting the 845 amp.  For rock and roll and large orchestraI movements I would usually substitute a solid-state amp into the mix to give me the slam I was in search of.  But the trade-off there is pretty severe as no solid-state amp I have heard over 40 years equals tubes for the upper half of the audio spectrum.  The closest I got to a great all-around amp was the 1978 Audio Research D-115 or D-70.  Very coherent across the range, but mids and highs were a bit shrill (wonder caps and circuits of the day).  The Doge 5, designed using the EL-34 power tubes, state of the art caps and a ton of transformer, is warm and coherent across the spectrum, with excellent SLAM and PRAT, a great all-around, day-in and day-out amplifier.

    Hi Marc

    Thank you for the Doge 5 it arrived today and I am blown away by the sound. It is similar to my Doge 8 with Cymer 150 monoblock valve power amps but on a smaller scale.

    Congratulations on a great design!

    I will be saving up for your DAC which looks great.

    Best Regards
    Andy
