Shuguang 12AX7 Pavane/Psvane Reference.

I was wonder if anyone has feedback about these tubes. They have a very good review at Positive Feedback.

I'm searching for good tubes to replace the "no brand" 12AX7 tubes that came in my preamplifier. Sadly the "perfect" tubes (50's NOS Mullards or Telefunkens) can cost almost the same that what my preamp cost. Also, I have heard about overpriced old tubes that doesn't produce good sound, simply because they are poorly matched. With the Groove Tubes Mullar replicas out of the market few years ago, I really don't know what should be my next tube investment.

Thanks for reading!.

I went for the TJ Full Music 12ax7's in my Nagra PLL. Replacing highly tested EH 12ax7's from the Nagra factory with about 18 months time on them (a few hours a day).

The TJ's slaughtered em. Wasn't even close. I thought my stock tubes must have been broken. better dynamics, lower noise floor, better imaging and detail. Not a single thing went backwards.

I bought 2 replacement sets. I think I need to by 2 more sets...plus my phono stage takes 12ax7's also...I'll try em soon there....

i tried 3 other tubes in my c.a.l. sigma 2 dac (besides the stock one). the last one was a psvane 12ax7, and i've stopped looking. it offered the combination i was looking for and since i only had to buy one, it was relatively cheap ($34.00). it was better than a j.j, nos phillips, and a g.e. 5751.

I have tested the Pavane/Psvane 12AX7's against NOS Mullards, Telefunkens, Amperex, and Mazda 12AX7's in my Pathos Acoustics TT RR integrated. The Shuguang tubes were the best all around, although the Mazdas were close.
Are your Telefunkens ribbed or smooth plates?

Rolling tubes with my Lamm ML2.1 made me curious for the Psvane 12AX7. I used normally Telefunken, Mullards or JAN Philipps as my favorite 12AX7. The Psvane is a great tube. Good gain, great image, deep soundstage and the high frequency area is top.
The same is for the Psvane 12AU7.
Good products for the money. I would buy them again.

The Psvane EL84 is an excellent tube, too.
