Are the CBS/Hytron 5814 considered to be the best 12au7 tubes?
They are the best sounding 12AU7 type tube I've ever used and I've tried a number of the best of the NOS 12AU7 tubes.WbWolfbane, what other NOS 12AU7 tubes have you tried? Would you consider the CBS-Hytron 5814 a significant NOS 12AU7 tube upgrade?]
I recently installed a New York Amperex 7316 in my Mactone amp, and it sounds very good. My only other frame of reference is an RCA 5814a. The only thing that is unusual is that it flares at start-up, but settles down immediately. Does anyone know what that is?

RCA, Raytheon, GE and CBS Hytron in 5814A tubes.Wb
The best 12AU7 is the ECC802 byTelefunken. They're simply amazing!Jim
I don't know that there is such a thing as best, but they are good inexpensive tubes which can make one very happy in the right circuit.Very true statement. I find each circuit and designer's use of the circuit to make a big difference on what tube sounds the best.
