The big 300B tube and amp report: Part 5   Topic List   < Prev Topic  |  Next Topic >
Reply < Prev Message  | 
Last night I took the big plunge. And what a pleasant surprise!

Eager to hear more of the TJ mesh, I threw caution out of the window
and inserted them in my autobias AN Kit One. This is having them work
at considerably higher disspation than the AES SE-1.

And HOW beautiful they sounded!

I had to listen really hard to compare the performance with the
Svetlana. Execept ONE thing, which is soon noticeable. The TJ mesh
sounded faster than the Svetlana in the Kit One. This is without
sacrificing ANY of the smooth leading edge.

And unlike in the AES, the TJ mesh yielded little to the Svetlana. If
anything it was a wee-wee-bit smoother in the upper midrange. It was
fully dynamic, with none of the whitening-out noted in the AES. The
Svetlana still have the upper hand in density of texture. The TJ
meshplate was a shade lightweight in comparison, but that, together
with the faster speed, had the occasional advantage of sounding more
buoyant and airy, especially with jazz cymbals and percussion, though
this was by no means always evident with other music. As I said you
have to listen real hard to tell. With bopping music it was also
apparent that the boogie factor is a bit below Svetlana.

Additional software: City of Sadness, soudntrack (Flying Saucer).
Shostakovich Predludes and Fugues, Scherbakov (Naxos).

With this superior performance, it appeared that TJ mesh preferred to
be run at higher dissipation. It would be interesting to run it in the
AES at 130-140 mA if I have a real matched pair. We shall find out
more about it when I take it to Andy's rig this weekend. His DIY 300B
amp runs at only 300V or so!!!!

Oh, haha, not at all. That was for my Lowther with its very weird positioning in my house....
