“Darkvoice 337: Introduction A little background: the Darkvoice 337 uses the 6AS7G dual-triode for its power/output tube which, while definitely delivering that special touch of midrange magic that I personally only experience from tubes, it is a far less syrupy tube than many. In fact, in the better amps, it’s a gutsy, powerful, neutral, very wide range amplification device. It does have a lot...” --Skylab
“ Good tube amp for the price. In EU Woo amps are too expensive, in US I would have bought a Woo most likely. But this amp is very nice! Edit: I upgrade a few parts inside (power resistors and output coupling capacitors) and now I can vouch this amp is world class! Such a pretty sound and power, it is scary good! ” --telecaster
“ I was lucky enough to pick this critter up from the FS/FT forum for a good price (thanks!). After spending a little time with it, I have to say I'm pleased. I've tested it with my Beyer DT770pro/80ohm and Senn HD205. Didn't do much for the Senns, but the Beyers seemed to become tighter and more responsive. It did give the highs a bit of a shrill feeling at loud...” --hdufour
The model uses two imported pentodes EF80 to amplify signal from the left and right channel respectively and tow imported triodes 6080 or 6AS7 with low internal resistance as cathode output of the two channels. The left channel and right channel are supported by different power supply.
