Coming in late again (I've been out of town for 10 days!). You should listen to a couple youtube videos that showcase the 6sn7 tubes:

In my own listening opinion, the tube that has the most resolution (and as a result, the most air) are the modern Electro-Harmonix 6sn7 tubes. Listening, it is possible that the PSVANE CV181-TII also has excellent resolution and air. It is hard to determine listening to this video, but the PSVANE tubes sound a bit harsh - though the amps and preamp stack are Behringer and Crest pro audio stuff. The PSVANE could be revealing flaws in the Behringer/Crest.
As far as all the tubes goes, the true Amperex tubes are the winner for me. For some reason, they had an immediate emotional connection with me whenever those tubes played during the video. The Amperex didn't have the resolution of the Electro-Harmonix or PSVANE, but they just reached out and grabbed me. The remaining NOS tubes didn't seem to have this magic. It can be very expensive to get "real" Amperex tubes. PSVANE is also very expensive. Electro-Harmonix are very cheap.
