To reflect on my experience with the Tung-Sol re-issue 6SN7, I came across a review of the Psvane CV-181-T MKII from 2012 by
Srajan Ebaen
on the 6 Moons website. This is how he described the Tung-Sol;
"any longer session should show that this effect is achieved
by shifting listener focus on more foreground data. One becomes rather less
conscious of surrounding supportive threads. This presentation felt more like
upper mid-level transistors. The prime quality was vivid clarity with a touch
of hyper focus and reduced depth of field"
Exactly how I found this tube in my system.
I
found it produced a very shallow sound stage and it did not have that
lush tube sound. I'm sure all of this is system dependent, so they may
sound totally different in a different preamp.
Ebaen 's review of the Psvane CV-181-T MKII came down to this;
"The Psvane tube played it denser. It soundstaged deeper, was
texturally wetter ('bloomier' or more luscious) and also felt a bit more laid
back and settled." "any rhythmically incisive complex-layered fare
filled out without getting even a tiny bit opaque or 'blended'."
I believe he was comparing the Psvane to
Shuguang's Black Treasure CV-181.
