When I owned a Mac C2300 preamp, the Psvanes were really nice--extended, harmonically rich, with good bass--the best current production 12AX7s I tried in there, and better than Tung-Sols and Mullards. I also liked them more than most of my expensive NOS 12AX7s in that preamp. Didn't try the Sovtek LPS, though.In the phono stage of my current preamp, a VAC Phi Beta, however, the Psvanes are fat, slow, and rolled off. I have three pairs and expected good things because the stock VAC tubes are obviously of the same construction (and probably from the same factory), although with steel rather than gold pins, but they sound completely different.
In the VAC, the Sovtek LPS are by far the best I've tried--clean, extended, balanced, dynamic, and extremely quiet. In fact, I prefer them to all the NOS tubes in my collection, including Tele rib-plates, RCA long black plates, and Amperex med grade. And I like them more than current production Tung-Sols, Mullards, JJ ECC83-S, Svetlana, and others. Jim McShane selected some really nice, super quiet ones for me. I like them so much I stocked up.
So you really have to take the plunge and try a few if you want to be sure.
