Customer evaluation for "Psvane 12AX7-T-MII/2 (=ECC83) matched pair"
16 Mar 2019

I have installed this tubes in an Universal Audio 2-2610S mic/line preamp.

My unit was a later one loaded with two ECC83S JJ's and two ECC81 JJ's wich after testing them

the way U.A. explains on their website did not appeared to be dead at all.

But at least sonicly they seemed lacking a bit of life to me.

Now I have just intsalled those Psvane a few days ago and even without burn-in time

the sound seemed to have more presence and definition on the bass, as same as an extend on the highs

compared to the JJ. Electric bass throuh it seems to get back the lack of bass there was with the JJ while keeping the

nice tube low-mid wich makes the preamp shine with this instrument.

The preamp has been running for like 60 hours now (day and night rotation with line sources) and it seems the middle and upper mids wich I found a bit uncolored at first, or more transistor-like sounding to say, are getting more lush and focused. That was the only thing I like with the JJ's, but the rest made it not suitable for my taste.

The most significant improvement compared to the JJ's is the differences you can get while running line-level sources throuh

the mic input. Impedance switching between 500 ohm and 2.0K Ohm seems more influent with the Psvane.

I wait for a longer burn-in time to see if there will be more improves on the sound since those tubes are known for having a longer burn-in time period than others. Anyway, for now, not having been able to test NOS RCA, Mullards or Telefunken in this preamp, it sounds like a serious improve above the JJ's. Very happy with them, I just hope they will stand the test of time...
