Full Music 12AX7 vs Psvane 12AX7-T

[jap]

Has anyone compared the Full Music 12AX7 or Psvane 12AX7-T?

Are the Sophia Electric 12AX7s just a rebranded Full Music 12AX7s?

I have been using the Psvane 2A3 Treasures for a couple of months - not 12AX7's but very fine sounding. Larry

I didn't like either. No comparison to even the standard NOS of yester-years like Amperex or Mullards.
