@ampus,
Message received. I want to follow up, but add some of my information regarding experiences with the Psvane T series Mark II and Reference series. The reference series are gold plated pins with gold etching on the glass compared to the normal Psvane series. Same with the T series MKIi. From my recollection, the reference series was replaced with the T series MK11, and perhaps, now called WE and ACME.
I used RFT, Siemens, JJ, and Sovteks in the 12AU7 position on my Octave Jubilee reference preamp. The Psvane imparted just music, nothing more nothing less. No overemohais of bass, highs, or mids. Just all fell in place. Yes, other tubes may have had more mid range but lacked bass, or that sparkle up top. This is my system so that is my impression. Compared to the classic Psvane, which sound more like Sovteks and JJs to me, the original Reference and MKIIs are stellar in performance.
With all the changes that have occurred over the years, my biggest question is how do we obtain the reference/MKII replacements? Is the Art series the new top of the line? Has the Art series replaced the MKII/Reference? I am little confused as I don’t see any ACME Psvane tubes.
