Psvane 845-HIFI or Shuguang 845B?

Phils experiences mirror mine. I had an 845-T fail in a very short period of time. I also greatly preferred the export grade 845B to the 845-T.

Hard to believe nobody has compared Psvane 845-HIFI series tubes (not 845T) to Shuguang 845B since Psvane 845-HIFI have been on the market for a while.
I've been using Shuguang 845B, really good tubes. Don't want to go for more pricy Psvane 845T, not only reliability problem but their sonic superiority has been questioned by some users.

Thanks!

Frankly, with the Psvane 845-T having been disappointing, there isn't a lot of incentive to bother with the more prosaic 845HiFi when the B tube is so reliable, cheap and good. It's easy enough to buy a pair of 845HIFI tubes online fairly cheaply, so if you're that curious, have a go.

Has anyone tried the cryo treated 845B from ATSI/Tubeman/Ken Chait?
