My TA is very, very quiet with the stock tubes. I have to turn up the volume on my Zana Deux SE to absurd levels to hear ANY hiss or 'tube rush'. At normal listening levels, the rig is silent. I have some Telefunken smooth plate 12AX7's (matched pair with balanced sections) that I intend to try, but I a extremely pleased with the stock tubes.
My Sunfire amp is very high gain, and I use the balanced output on my Cary, so I never, ever get to 9:00 on the Cary's volume control, even in full-tilt boogie. But I think a phono amp should be quiet well beyond what are reasonable listening levels.
Again, though, the Transcription is that quiet, with the right tubes.
