Another Great Tube Compliment for the 336i
JAN-CRC/RCA 6AS7G black plate in the rear, with the 1952 Sylvania "Bad Boy" up front is a terrific combination. Very dynamic and detailed, with deep, powerful bass. Bob James' "Hi-Fi" SACD (a compilation of his more popular compositions) sounds super through the 336i and Beyer DT880's. [Just got some new PS Audio XStream power cords, too: w/silver coated, solid core copper conductors. They've brought some nice added detail, frequency extension and sense of space to the sound (although sacrificing just a tad of mid/bass weight and warmth), compared with the DIY, ErnieM cords I was using before.] Want to try the RCA 6AS7G gray plate, or possibly the Svetlana 6H13C, in the rear before the end of the day.
FYI, there's a British dealer on e-Bay selling NOS Mullard 6080's (for about $25USD/shipped). You bet I'd like to try one. The two, other 6080's I've tried so far (GE and RCA) tend to sound a bit overly "coiled" and either unresolving or unopen with the DarkVoice (although the GE6080/Sylvania 6SN7GTB sounded very nice, as I recall). If these Mullard 6080 tubes offer that rich, pure and tonally textured sound that other Mullards are known for, they're certainly worth a go-round with the 336i!
One "downside" to owning a nice tube amp like the DarkVoice is that you can spend more on tubes than you spent on the amp. So far, I've spent probably half the purchase price of the 336i on tubes. But, it's been a fun, educational and rewarding experience all-tallied.
