The new Audio Research Ref 110 stere TAD = 929Belles 350A TAD = 649
Bel Canto REF 100 TAD = 24897 (There is an issue of where to take the noise floor on this one so it could be substantially lower)
KR VA340 at 1 watt TAD = 190 (not 150 sorry for the slightly incorrect value above)
KR VA340 at 10 watts TAD = 3900 (this is near clipping for this amp)
Vincent Hybrid monoblocks TAD = 406 (not bad!)
Manley Mahi Monoblocks TAD = 37446 (again this amp is significantly more linear at 1 watt than at 10 watts, which is near clipping. However, no 1 watt data are available.)
It is not so easy to determine what is the true noise floor of the amplfier in many cases. As a result these are estimates and nothing more. One thing is for sure, many many many amps do NOT have a clean noise floor. Most seem to have a lot fuzz that I guess could be IM with the power supply and distortion or the 1Khz fundamental.
