(My 90's vintage still sounds good with very good (no -exceptional) isolation and conditioning. (Sound Application, Equitech & MIT). SPECTRAL claims faster today. OK. Mid 90's hot cars went 205-210, todays 210-220. Does it make any difference to the music?
The 'fastness' (or 'slowness') of circuitry isn't something that can be picked out by ear. When distortion is low, the music sounds good. Making circuits 'faster' is just one way among many of lowering distortion.
It's interesting some don't feel you can hear speed : - ). That's ok; many don't think one can hear polarity );? Does anyone out there appreciate appropriate polarity for the recording?
We've had a polarity switch on our preamps since 1989. Its only audible if the recording uses a minimalist microphone technique, like two mics to record everything.
