Hi, I thought that too...about 10 years ago. It sneaks up on you. Especially if you are like me and constantly trying to improve existing gear. Right now I am pushing for all the diy tube gear to at least meet a wide-band -95 S/N. Only the phono preamps are a little behind that goal (-88 t0 -90 depending on the variation). As you might guess I really hate hum and noise. If I can hear it or see it on a scope then it has to go regardless of how long it takes. BTW the very earliest phono preamps (ca 2010) were horrible at about -65. One variation could find a power transformer or other source of hum at 5 feet away. Yikes. Not any longer.

Good Listening
Bruce

I understand completely, but I'm a bit less picky, I think. What RIAA do you use now?
