Yes! This is what I have been saying...tremendous tube! Just did an extensive comparison between the Philips-Holland E88CC SQ Halo getters (1960s date code), the Amperex US PQ 6922s and the 6n23p Voshkod Rockets 1979, 1980, 1983,etc...date codes.
The 1979 and 1980 Voshkod rockets sound better then the Amperex by a mile and even beat the SQs in most respects.
One note: I have collected a large stash of these V-Rockets and I noticed their seems to be two versions across date codes. One with a long gray shield and one with a long shiny shield - kinda' like the S&H CCa. Except the sound on the V-Rockets with the shiny shields sound way better! Much more open, with a more extended and detailed high end (unlike the the S&H CCa where the gray shield are superior). I have posted a picture, the shiny shield is the 3rd from the left and the gray the last to the right.
Try them both, but don't judge them until you have heard the shiny version. Best sounding of the date codes are the 1979 and 1980s so far.
V-Rocket vs the Amperex - way more detailed, just as musical, wider deeper sound stage, way more dynamic and open, deeper tighter bass.
V-Rocket vs the Philips- Holland SQ Halos - the V-rocket again excel, the SQ are a tad more liquid in the mid, but the V-Rocket beat them in dynamics, openness, with a wider and deeper sound stage. Both tubes are very musical, but the V-Rockets have a deeper level of detail. The detail is so great that I could things like light cymbal taps and guitar plucks that I had never heard before, even on recording that I've heard hundreds of times! This level of detail adds to the ambient clues that provide a very realistic 3-d sound staging. The musicians are holographic vs stacked flat cardboard cut-outs.
The 1979, 1980 vs later 1980s and 1990s V-Rockets.
They are all very close, but the earliest date codes are the best - with a more dynamic presentation and greater detail. I'm arranging to acquire some 1960s date codes so we'll see how they sound.
Awesome tube! especially for the money!
