Linlai Elite vs Psvane Acme 845


Personal experience with the two tubes.  What is the difference between both tubes, which tube has better SQ and which tube do you recommend?  Thanks members!!

I purchased a pair of Linlai tubes (from Grant Fidelity).  I had my preamp serviced recently and discovered the tubes test low.  The technician stated they tested lower than any other 12 or 6SN7 that he’s tested.  And this was coming from a tube audio manufacture that utilizes a David Berning design.  The tester reached out to Grant Fidelity to determine why this was the case given the tubes were purchased in Sept. 2022 and it’s October 2023 (13 months).  He didn’t receive feedback to date.  I contacted the company and this is the received response:  For within warranty period, please read below for our position of 3rd party measurement. Tube factory maintains its own product quality control and credibility to its own measurement procedure.

So far i would pick the Psvane ACME 845 tubes.  Better highs, midrange just right bass is very articulate.  With the mesh designs, teflon internal structure, super black plate, really nice sounding tubes, super clean and transparent.
