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.

Doge 8

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.


I don’t think anyone in the world has listened to all brands of tubes available of a certain type. The Amperex 12AT7 is the best sounding 12AT7 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, the JJ 12AX7 is an excellent sounding tube, not at all bright but very detailed. It’s also very cheap, but don’t be put off by its price! Apparently it’s a Telefunken design. Don’t be a snob and dismiss it because it’s cheap… . EI have been making tubes for ages…

Good source for valves, especially the Amperex 12AT7 is the ‘bugleman’ on ebay,  in Hong Kong. he does not list everything so email him

The JJ tubes are freely available on ebay.

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 or silicone rings you can buy on ebay and I recommend.

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 and fit those neoprene ir silicone ring tube dampers. Install the best 12AX7’s you can find. I use the very reasonably priced JJ tubes… Everyone has their preference but the JJ is very neutral and will suit all systems. The Amperex 12AT7 however is the best of its type I have heard. You need not worry about the 12ax7 on the very left (looking at the front) unless you use the balanced outputs.

EVATCO tubes in Australia

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.
