Had a listen to a pair of new production 6SN7s, just to see if they have closed the gap (sound wise) on the great vintage stuff. The 6SN7 is branded Full music with a brass base ($185) this tube is not cheap and has a good reputation as an excellent sounding tube. Its opponent is a pair of brown base Mullard 1950s ECC32 ($800) considered the best sounding 6SN7 variant. To my surprise the full music does sound very good indeed, typical Chinese sounding, a little soft, polite, lacking leading edge, vague, Its sins are of omission rather than commission, and also on the plus side it was not dark, and most important, it is musical. Probably tuned for the modern typically hard analytical cd players that predominate the landscape, Have the newer tubes reached the level of the vintage tubes at this time. Not yet, but they are getting closer.
