Quietest amp you ever owned ?

A few years ago I had the little Antique Sound Labs MG SI 15 DT integrated and was impressed how quiet it was; in other words with the amp on and no music playing it was dead quiet when I put my ear right up to the drivers on the speaker. I am curious what other amps out there are as dead quiet since most amps have a slight hum or hiss that can be heard when music is not playing. At the time I was using Coincident Conquest speakers which are pretty efficient.

Yamaha MX1000U
(1979 - solid state, 760wpc @ 4ohm; 960wpc @2ohm; 460wpc @8ohm) which I still use with fabulous results. I am amazed that for the power output and the cheesy original power cord that this monster does not put out ANY noise. Totally clean.
Even my CR-1020 (1978 - 90wpc @4ohm; 70wpc @ 8ohm) which is in a separate system performs in the same quiet manner.
A while ago I sold my much newer Mac and a Krell but kept the Yamahas. Do it again Yamaha ... where'd you go.

Bob,
The 80 can't be compared to anything Dynaco originally produced. I've played with 70's and even had a pair of fully restored/upgraded MKIV's. Nothing can touch this amp. Panor+25 years of technology really made a difference.
The re-release of the 70 should be quite nice also. Finally, I do believe there is a 160 out there.

My nomination is a tossup between the Tom Evans Linear A and the Wavelength Triton. Both are quieter than any of the SS amps I've owned - so quiet that with my ear inside the 97dB speaker cones I can't tell if they're running. This is with the Tom Evans Vibe line stage, because all the other preamps I have except for a TVC add way more noise than either of these amplifiers.

Noise on the Wavelengths was measured during construction at .12 mV or 120 microvolts... Both are super-quiet, but the Linear A manages to put more music in front of that black background - but that's a topic for another thread.
