JJ 2a3-40 v. biplates

Posted by andy evans on July 12, 2012 at 23:54:55:
I've had one email with another view of the JJ 2a3-40:

"I don't recommend the JJ2A3-40. A very powerfull bass and dynamic sound.
Excellent macro dynamics, but not so good in micro. It's a Naim like PRAT
tube. The even more problem is the glare in upper mids and highs. Your
fullrange speakers are high resolving and the aluminium cones are sensitive
to glare."

This goes on to recommend the black coated glass dual Monoplate 6B4G or 6A3 as transparent and a very refined sounding tube. Not harsh.

This could be something like my own limited experiences. I do like biplate old Chinese 2a3 and 6C4C Svetlana. smooth sound. I haven't found many monoplates that I like. In 2a3, Sovteks all have that glare. In 300b I don't like Sovtek or EH 300b. Haven't heard Svetlana. Best I found were the Chinese ones. In fact I prefer just about all the Chinese ones to the Soviet ones.

I haven't heard any EML.
