I got to meet one of their chief analog guys in 1988. The usual response from friends when I made them a tape on my Nak. was, "What did you use, I can't make my tapes sound like this?" The tapes sounded good on even much lesser machines (I noticed the same effect with video tapes make on my prosumer Panasonic machine ~1982). Never needed Dolby, either.

John is quite correct to use known good components and they are audible but what can we measure to move forward?
Thanks for the info, I was hoping that it was a more apples to apples comparison of different designs that yielded similar musical qualities. Although 100db is a good listening microscope! You can really hear well into the part of the music/recording that makes it sound real.

I believe measuring for differences at -100db and below to be in question; when I hear one preamp sound real and another sounding not real, the differences are well above this level. Trying to measuring this would require a bit of sideways thinking.

What is a glow FET? Never heard of this device and it doesn't seem like a typo. Thanks!

Mike

I wonder what the spectrum of that looks like.

To Chris Hornbeck,
Can you elaborate about "ground contamination caused by the (series) power supply regulators" ? Is it a rectifier diode switching noise or something else?

Thanks
Sergey
