I have tried the Mullards, Telefunkens, Sylvanias, Brimers, and RCAs in my Lector CDP-7T CD player. The Mullards always sounded the best to me. However, I recently bought a pair of the new Gold Lion Genalex 12AT7s and in my system they are the best of all of them. They seem to combine the best of the Mullards and the Telefunkens. I have also put the new Genalex tubes in my preamp (6922s) and in my phono preamp (12AX7s) and could not be happier. I think I am done with $400 a pair NOS tubes for good.
