This brand deserves its own page here. The name refers to the Doge of Venice, who in the middle ages was the head of that illustrious state. It is pronounced doje, the ‘o’ and final ‘e’ as in ‘rose’, the ‘j’ as in shhh, NOT dohgay as touted on the net.

First of all, I have no affiliation or financial arrangement with this brand. I simply list it here because it ranks with NotePerfect as one of the best brands in its field.

I have been recommending this brand for many years… when I had my shop I told my customers to buy the preamp and the CD player even though I did not make $1 on it because they are such superb products and since then I have not heard about a single breakdown among all these sakes. I still use the preamp and their DAC

Doge is the brand name of an ODM manufacturer in China who makes some of the German designed LUA electronics. For copyright reasons they have slightly different cosmetics. The Lua equivalents sell for thousands of euros! The only thing that happens in Germany to the Doge units is having the tubes put in.

Not only is this the most dynamic, neutral and transparent line stage I’ve heard, the phono stage is equally brilliant, beating a Marantz 7c phono stage I had made, which was dual mono, had an outboard power supply and used modern parts!

I am familiar with and use the Doge 8 valve preamplifier and the Doge 7 DAC. For the money they are unbeatable, excelling in sound quality over other brands costing the or four times as much.

This preampilifier has received accolades on other sites, mainly on Arthur Salvatore’s where it sits just below mega-buck preamps.

Best valves:  The most important valve is the 2nd one from the left, looking at the preamp from the front. it’s the line stage amplification valve. This valve affects the sound of the preamp dramatically and also influences how much tube rush you will hear from the phono stage.

Tubes for the Doge 7 and 8

The Amperex 12AT7 is the best sounding I have encountered – the texture is smooth and velvety, yet detailed. Musically this is the most involving 12AT7 I have ever heard. Replace all 4 12AT7’s with this valve.

For the phono stage, JAN GE 5751 are excellent and my preferred choice.

Good source for valves is the ‘bugleman’ on ebay,  in Hong Kong. he does not list everything so email him

I like the sound of this amp and the DAC without the springs in the towers covering the tubes. I’ve never liked what tube dampers do, except those red neoprene rings you can buy.

The Doge 7

This is the most natural CD sound I have heard, especially on a musical level.

Many of us here agree. And collectively we have heard a lot of digital front ends!

It’s almost analogue in sound, but that does not mean it softens the sound. Like the preamp it is utterly clean sounding. Piano sound has that natural  shimmer that you hear live and on vinyl and strings sound sweet (!!) with all the upper harmonics CD is capable of; in fact there seems to be a whole layer of upper harmonics that I have not heard before. There is great transparency, too and perfect coherence, just like the preamp.Best of all it is very involving – you hear how the musicians play. Nuanced, agile, an with excellent dynamic shading and great bass weight. And a lot of energy when it’s there in the music – this is one area where most digital components fail misearbly – they just sound lifeless. 

Playing high resolution files this is unparalleled sound. It beats master tape copies and everything rise. You are there at the recording!

Unscrew the towers that cover the tubes and remove the springs and Teflon discs from them; once you have put in premium valves, replace the towers but not the springs. Install the best 12AX7’s and 12AT7’s you can get …. see above: Doge 8.

For my system I replaced the 12AT7’s with Amperex 6072A, it’s not as bright, more analog, more color.

EVATCO tubes

When I had my shop I directed many customers to this company for tubes. I recently bought some for an amplifier I ended up not buying but they refused to take them back, despite the parcel not having been opened. This is not good business after so many years! So my suggestion is to STAY AWAY and GO ELSEWHERE. Amptubes and vicmazz on ebay are excellent.
