Jax2 was very helpful providing me with his MW TP tube rolling Cliff's Notes, and in my system, the EML 5U4G and Tung-Sol 6SN7GT round plates have produced the best sound. Thanks, Marco.
I don't use my MW TP as a reference component, so since absolute, optimal sound is not a priority, I'm perhaps more forgiving about subtle differences in tubes than others. I found the Russian 6H8C from Upscale Audio were close enough in sound to the Tung-Sol round plate to cause me to sell a second pair of TS round plates that I had purchased. They are *not* the same, and there *are* definite differences between the two. The Tung-Sol has better balance, tighter bass, and slightly smoother highs (everything that causes these tubes to sell for the premium they do).
The RCA 6CG7 cleartops are also very good.
Many people would be quite satisfied with either the RCA 6CG7 or Russian 6H8C, IMO.
