Re: Which low cost 12AU7?

My experience with the Electro-Harmonix 12AU7 in this preamp vs the Mullard JANs ($35 each) is that there is nowhere near $100 worth difference in total cost between the 2 sets (of 4) tubes.

That's why I believe I can get a $9 tube to equal the performance of the Mullards by circuit tweaks and/or cryo - I can get the cryo done for almost nothing by putting 4 tubes the box with a bunch of other stuff going out for cryo. The Mullards are only a little more open/transparent, dynamic and "sweet" (harmonics, shimmer, smoothness).

I'd just get more E-H tubes, but never having heard the others in the same price range, I had to wonder if any of them were demonstrably better performers. I have a pretty strong bias against the Chinese Sino tubes after never having been happy with the sound of any Chinesse tube I've tried in a preamp or amp. But I don't want to discount anything at this point.
