FIRST REVIEW OF DOGE 7 on TNT-AUDIO.com  http://www.tnt-audio.com/sorgenti/doge7_dac_e.html

 

 

Since 2013 many of you encouraged us to design it . We worked on it during 2.5 years. It is now there, ready to ship. The DOGE 7 is our most innovative product ever. It combines the best of digital and analog worlds and offer a sound that is so close to turntable sound that is will bring vinyl lovers into digital world.

It offers at the same time a 32bits/384KHz chip that is DSD compliant and a full tube analog stage without solid state components, where most of the other tube DACs on the market offer just a buffer tube stage except a few ones that can be counted with fingers of one single hand. One is the polish “Lampizator” at 3 to 5 time our price depending model, or the UK “Audio-Note” at 7 to 15 time our price depending model.

DOGE 7 uses a 32 bit last generation ESS Sabre ES9018 and a 6 tubes analog stage if you use unbalance outputs or 8 tubes analog stage if you use balance outputs.

We have two coaxial inputs, two optical input, one AES-EBU input and of course one Hi-Speed USB input up 384Khz ! We use famous XMOS chip to have our USB input to get full benefit of HD digital bitrates, where 90% of the DACs on the market get only 96KHz on their USB input.
 
There are many DACs on the market with ES9018, but none of them offer such an analog stage like the DOGE 7.
Like in our CDP DOGE 6, after the ESS Sabre chip converts the signal from digital to analog, the analog signal is only treated by vacuum tubes, we do not use solid state chips to make the amplification. The result is an incredible “analog” sound that makes DOGE 7 sounds more like a turntable rather than a DAC. Some A/B test done with some other DACs has shown DOGE 7 easily recognizable in 
all tests.

 

We use the best components in DOGE 7, golden plated sockets for the tubes, UK ClarityCap ESA model for our coupling capacitors, Nippon-Chemicon and Nichicon for Electrolytic caps. The digital section uses ultra low noise voltage regulator.
 
The DOGE 7 comes with a quality headphone output with volume controller. Please note the headphone output is the only solid state stage on the DOGE 7. It would have been impossible to have a quality tube headphone output according the size available inside the chassis.
 
The same potentiomer offers as well a volume control, called “preamp mode” on the display. However that doesn’t mean you can use the outputs of DOGE 7 in preamp mode to drive directly a power amp as the max voltage is the same in DAC mode or Preamp mode. This volume function is controlled by the ES9018 chip. Its main utility of this preamp mode is NOT to replace a traditionnal preamp but for example to manage volume with integrated amp that has no remote controller. It can be used
 
DOGE 7 comes with a elegant and discret display that shows :
> the bitrate
> the input selected
> the digital mode PCM (traditional mode) or DSD
> the output mode. Standard DAC mode or preamp mode.
 
Both analog and digital connectors are golden plated and first grade sourced in Taiwain. You will be surprised how our digital connectors are different from mass market DACs. They are same quality than those you would find on $10,000 DACs.

  1. 5 out of 5

    I was looking for a tube dac to impart an organic sound into a second system. Owning a lot of NOS tubes I decided on the dac 7. What a fantastic dac! I brought it into my main system just to play with it and I don’t think it’s leaving. Fantastic sound, build quality is top notch, and this dac plays every resolution in my playlist without any problems. I have been lucky enough to have a Lampi Big 7, the Zanden dac, and several others, and this new Doge dac ( with the right tubes) can play with the best of them. I’m VERY impressed.

    Hi Marc,

    I received the Doge 7 earlier this week, and so far I am really enjoying the sound – I have compared it briefly to my excellent “analog sounding” Border Patrol Non-Oversampling (NOS) DAC, and I hear that the Doge DAC provides a touch more detail plus a deeper sound stage – And this is even before the Doge has had a chance to fully break in. I believe this DAC is a keeper! After some more time with the Doge, I will be happy to write a review for you.

    Best Regards,
    Gary

    After purchasing and then spending some time listening to my new Doge 8 Clarity preamp, I was enamored enough with the sound and build quality of this single-ended class-A design that my interest turned to the Doge 7 DAC as a potential successor to my then current DAC. I’ve owned several DACs over the years of varying designs, but never an all-tube unit (and single-ended class-A, at that) with an ESS Sabre processor. So, after a few email exchanges with Marc who answered each of my questions quickly and completely, I decided to order a Doge 7 based on its promising specs.

    I received the Doge 7 directly from the factory in a few business days (triple-boxed surrounded by a wooden crate!), and upon first listen, I knew something special had just arrived – I then allowed full break-in to occur over the following weeks, and all I can say is that wow, this DAC really conveys music with heart – Abundant detail and spacious sound stage, along with a nice dose of holographic presentation, without treble glare or other frequency spectrum artifacts (the bass region also being tuneful and deep) – All of this producing a convincing “musicians in the room” effect, which other listeners have also noted – This DAC is a keeper!

    Build quality matches that of the Doge 8 in every way, meaning a lot of excellent hardware especially for the price paid (for example it as well utilizes Clarity coupling caps), and is simply a great match for the preamp. I also own all-tube amplification driving electrostatic speakers, and the system as a whole is wonderfully involving and satisfying – Thank you again, Doge, for another excellent product.

    Translated by Doge team from french customer review.
    I am the owner of a DOGE 7 since one month. I received it in a very robust packing (foam, 3 carton layers + wood frame). So very serious packaging. On my opinion the assembling quality is just one little step below the made in Europe or made in USA products, but no really serious matters. The components quality is perfect.
    I tried a tube rolling and felt that the DOGE 7 has still a margin of improvements with higher range tubes.
    The sound is dynamic, rich, natural and warm. This device offers a killer price/quality budget. I recommand it without any hesitation.
