@aricaudio ...I have tried the PsVane CV-181 (6SN7) TII which are very similar, if not identical to the ’guang Treasure CV-181.
Hi Aric, do you recall how many hours you put on the psvane before they settled in and your final conclusions were made on their sound?

Early Update:
@rocray During early burn-in first 75hrs the PSVANE CV181-TII do offer a slightly unique sound compared to my best vintage or Fullmusic 6SN7s. Super Easy to listen to right now with lossless streaming on R2R DAC, so far. Sitting in my Cary SLP-98 preamp (wider tube glass base barely fits). As new, requires 60 min play for the SLP-98 warmup then it opens up. Sorta liking the midrange tone better than my best vintage 6SN7 tubes. More similar to Fullmusic 6SN7 sound, maybe a tad smoother on top, soundstage opens up even more at 120 minutes warmup of ’98 for whatever reason, i dont know. Needs more burn-in / cycling on off settling time though. Not disliking them yet, staying put. We will see. Will decide more at 100hrs burn-in. My FullMusic 6SN7s warmed up faster (set point?) after 100hrs burn-in for whatever reason. Simply trusting my ears at this point.
