I certainly hope it is "the best possible sound from a line-stage preamplifier".
Hi John, just a thought on a possible noise source (and this may be opening a new audiophile can of worms). Do you have any compact fluorescent lights (CFLs) in your testing area? Those buggers emit RF; they may also dirty up the A/C as well, I don't know. Just hold a cheap AM radio next to one and have a listen. I won't have any in my listening room--they definitely degrade the sound. In fact, I try to have all CFLs turned off on the entire floor that my listening room is on, when I'm using it. Regards!

Yes I do! I don't have the Lamm available anymore but I will try replacing the CFL with a normal light bulb and see if I can change the measured noise level with a different preamp.
A subsequent discussion with Vladimmir Lamm revealed that he measures wideband signal/noise ratio with a 110kHz bandwidth whereas I use 500kHz. That would explain the differences in our measured results, especially as I have the CFL in my test lab.
