Which tubes to buy

I have an Audio Research Ref. 160s power amplifier. It's almost time to replace the tubes. This will be the first time I replace the tubes in this amp. In the past I have purchased tubes for my Ref. 6SE preamp directly from Audio Research or Upscale Audio. Audio Research furnishes Tung-Sol  KT 150 tubes with the amp. and also as replacements. Recently I have found PSVANE brand tubes available. Does anybody have experience using these tubes? I'm trying to get the best sound quality. Tung-Sol made in Russia have been around a long time. PSVANE made in China is new to me. Any suggestions or recommendations?

I remember that many years ago, Psvane tried to make a KT120 and they were notoriously unreliable. Maybe they’re better now, but there’s no way I’d trust a new KT150 from them until it’s had a lengthy, good track record under its belt.

You could ask ARC their thoughts on this tube, but my guess is they won’t be too keen on that. Upscale doesn’t sell JJ or Psvane tubes for a reason.
