The Darkvoice 336SE Tube Headphone Amplifier uses two great sounding tubes - the 6SN7 and the 6AS7. The 6AS7 must be the current emperor for tube headphone amplifiers. Of course the 336SE being a product of Chinese origin comes stocked with Chinese equivalents, these may be good tubes but in all honesty they do not do any great justice for the amplifier. Naturally I have tube rolled my 336SE with an RCA 6SN7GTB and a GE 6AS7G Coke bottle tube which are a great sounding duet. Of course there are many other rolling combinations and it all boils down to personal taste.
Darkvoice 336SE is a product of Orphean Sound Audio-Video Lab of Chengdu, China. Chengdu is not a place you would immediately think about producing such products. Visit them at "Darkvoice"
I am still burning in my tubes but the sweet tube sound of these two tubes is breathtaking. I will write up some more on the sonic attributes of this lovely headphone amplifier in the days to come, but there is already a growing fan list with many threads on the 336SE on Head-fi and a simple search would reveal many threads.
For now I will leave you with a teaser of some photos of my 336SE (These were taken earlier with the stock Chinese tubes, further photos will be posted of the new tubes):
Rolled tubes: Photo 1: Early vintage BLACK-PLATES-SILVER-LETTERING General Electric fat-glass 6AS7G "coke-bottle" audio tube. Base code "8-17, 188-5":
