6922 tube recommendations

A couple of years ago I purchased a Musical Fidelity x-can headphone amp. I followed MF's directions and left the thing on all the time, and eventually the tube burnt out. I bought a cheap replacement and it sounded like crap. Specically it had way too much noise to be enjoyable at moderate volumns. I basically haven't used the amp since then.

Given that my wife has been busting my chops for playing my music too loud at nights I was thinking of bringing this amp back into the rotation. However, I need to replace the tube before even considering it. Does anyone have a recommendation for a good 6922 tube? tried searching the forums w/o much luck.

thanks

Those $35 cryo'ed 6H23 tubes are a steal. It's only that the supply is greater than the demand right now since not too many people know of them. Soon when word gets out and the few ( <100 ) out there are gone, they're gonna re-sell for hundreds. Even if you don't like them, keep them and sell them for double that in 1 year.

PS: I'm not the guy selling them :-)

I just bought some Platinum grade Amperex 7308 for my preamp from Kevin @ Upscale and VERY please with the transaction and tubes. Ordered Sat and delivered Wed.

Brendan @ tubeworld is a good source. His prices are on the high side but all legitimate top quality stuff.

I've also had very good luck with Chris Johnson @PCX. Reasonable price with helpful advice.

I can vouch for Kevin at Upscale. I recently purchased 7308 and 6H30. Great tubes and great service. Also picked up equipment and couldn't be more pleased. Highly recomended. Jim Mcshane also great to deal with.

I've used a pair of Russian "Rocket" logo tubes in my preamp for a while now. I got them from Upscale Audio, but you can actually pick them up for about 1/4 of the UA price on e-bay (I recently picked up some back-ups). Just make sure they are the true "Rocket" logo on them. The Russian logo's determine the manufacturing plant over in Russia and for some reason the one's with the rocket on them sound best and don't go microphonic as easily. You need to research the Russian tube factory logo's on-line to identify the proper factory name (Voskhod, Kaluga).
