Rolled in some new tubes (uh, sorry . . valves) tonight.
The Telefunken E88CC/6922's sounded really beautiful, until one crapped out after a couple of minutes. Hopefully the seller has more.
Next, the Voskhod 6N23P silver shields, 1979. These are some very, very nice tubes at a reasonable price. Can't listen long enough to do a complete review, but suffice it to say . . . grab some if you can. They are particularly nice in the mids and highs, and this with no burn-in. I bought 4 from a Ukrainian seller - electrikua (Protek Trading Services, Inc). - and he/she was good enough to throw in an extra tube, no charge!
R Scott Ireland - sounds like good initial impressions, I agree with your take, I'm hearing very similar things. These 'valves' are crazy cheap, glad you could get some.
Well tonight I did a fairly extensive listening test between the Voskhod (that's how the Ukraine Dealers spell it) 1979 Silver shields and the PCC88 SEL Lorentz.
The SEL have lots of detail, deep and tight bass and a very wide sound stage. But after listening to some of my tougher recordings like Florence and the Machine "Dog Days", the SELs betray a little harshness, especially on female vocals. The Voskhod '79s are just as sweet as can be - very liquid in the mid range to upper mids - a lot like the 1960s Philips SQ Holland Halo Getters. After about 15 minutes with the SELs I was finding the sound a little fatiguing, in contrast I can listen to the V-Rockets all night without a problem.
Another thing I noticed, the VRs had a more dramatic presentation, maybe a bit more marco dynamics, it definitely adds to the fun.
I would have to say the VR are a little darker then the SELs, which is perfect for my HD800/Moon Black Dragon V2 combination and the extremely transparent DAC I have. And will be perfect for my new cable I'm ordering for the HD800s - the Stephan Audio Arts Endorphin.
Maybe for some with Orthos they may prefer the SELs. Also, these SELSs have only about 50 hours on them, so they could use at least another 50 hours burn-in. I'll do that soon and update if my opinion changes.
