The DOGE 7 is our most innovative product to-date. It combines the best of digital and analog worlds and offers a sound that is so close to turntable sound that is will bring vinyl lovers into the digital world.

It offers a 32bit/384kHz chip that is DSD compliant together with a full tube analog output stage without solid state components. Most tube DACs on the market offer just a buffer tube stage, except a few that can be counted on the fingers of one hand. One is the Polish “Lampizator” at 3 to 5 times our price depending on the model, another is the UK’s “Audio-Note” at 7 to 15 times our price, again depending model.

The DOGE 7 uses a 32 bit  ESS Sabre ES9018 chip and a 6 tube analog output stage if you use unbalanced outputs or an 8 tube analog output stage if you use balanced outputs.

We have tried to offer as much input flexibility as possible with two coaxial inputs, two optical inputs, one AES-EBU input and of course one Hi-Speed USB input capable of data transfer rates up to 384kHz! We use the famous XMOS chip to enable our USB input to get the full benefit of  High Res digital bitrates, whereas 90% of the DACs on the market can only manage 96kHz on their USB input. As for analog outputs, we offer two pairs of RCA phono and 1 pair of XLR outputs.

There are many DACs on the market with the  ES9018 chip but none of them, except our DOGE 7, offers a pure analog output stage.

In the DOGE 7, as in our CDP DOGE 6, once the ESS Sabre chip converts the signal from digital to analog the analog signal is handled only by vacuum tubes. We do not use solid state chips to make the amplification. The result is an incredible “analog” sound that makes the DOGE 7 sound more like a turntable than a DAC. A/B tests done between the DOGE 7 and other DACs have shown the DOGE 7 sound to be easily recognizable.

 

 

We use the best components in DOGE 7. Gold plated sockets for the tubes, UK ClarityCap ESA model for our coupling capacitors, Nippon-Chemicon and Nichicon for Electrolytic caps. The digital section uses an 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 considering the limited space available inside the DOGE 7’s chassis. 

 

The same potentiomer that controls headphone output also offers a volume control, called “preamp mode” on the display. This volume function is controlled by the ES9018 chip so the maximum output voltage is the same in DAC or preamp mode. Preamp mode is therefore not intended to be used to drive a power amp directly but rather to be used to match the DOGE 7 output level to that of your other source components or to allow you to benefit from the DOGE 7 remote control function if your integrated amplifier does not have one.

 

DOGE 7 comes with an elegant and discrete 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 analogue and digital connectors are first grade gold plated items sourced in Taiwan. Also, you will be pleasantly surprised how our digital connectors differ from those in mass market DACs as they are of the same quality as those you would find on $10,000 DACs.

4 reviews for DOGE 7 – Tube DAC

  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.

    I bought the Doge 7 because of the suggestion of a friend, without the opportunity of auditioning it, and with some reservation about the worries that in Italy may not be a good place for repair it (inside or not the warranty) in case of problems.
    My system is an analytical one, and despite i really like to have lot of details, something was missing in the overall emotional impact.
    I wanted some more “meat” at dinner, the flavour of it, the smoke departing from its body and its taste under my teeth. But i didn’t want to lose the accuracy, the elegant presentation and the science of a real gourmet dish.
    My first choice was to match my Musical Fidelity A5 Integrated Amp with is “brother” MF A5 Cd Player, of which i was interested in the valve output stage, but unfortunately the ex demo i found was damaged and didn’t work.
    This was sad to me, because on the paper it could be an ideal match, sonically and esthetically. The next step was to find another valve cd player, but my friend suggested to go further and take a Valve Dac, because the future is not on cds, and because it could read my cd collection (5000/6000 discs) very well, bypassing the cd player Dac. So i arrived at Doge, and what i’ve seen and read about the Doge 7 was exactly what i was hoping to find, expecially the union of high definition (via the Sabre chip) and the 100% tube analog output…on paper “the best of both worlds” (by now a new audiophile cliché).
    Now it’s only two days i have it in my home, and the first thing i can say is: outstanding! It’s not a cliché, it’s real. I lost nothing about details and acoustic scene (on the contrary, it’s even better than before), and what i get is exactly that involving, natural, real feel of the instruments and the ambiance in which the music is played. The tones of the instruments are just so right, pleasing and with the correct balance between them, that the concrete feeling of “being there” is naturally avverted. I also noted a big improvement in the low frequencies…good, deep bass with body, punch and control.
    The best thing is that the tubes are nothing near the raccomended break-in period, the sound is already excellent and it can only improve!
    By now i’m only listening to my cds collection, and they are revealed in the best way i’ve ever listened; i can’t wait to test some seriosi hi-res file (which by now i don’t have) via USB from a dedicate PC.
    No problems with expedition and installation.
    Excellent!

    This is a fantastic DAC and amazing value. The DAC really shines. It bested my other Stereophile Class A DAC. It has gotten my digital sounding so close to my vinyl front end and, in some cases, it’s better.

    Customer service and shipping were superb. Doge got the product to me so quickly without hickup.

    I think the stock tubes are fine but you can do much better by rolling the tubes.

    The build quality is great and the pictures do not reflect the super fit and finish of the unit. The sound quality can be near spellbinding. I’m very pleased! Buy with confidence.
