The point is that (using 0-100 scale) volume 70 = 15dB of attenuation = SNR decreased by 15dB from 96dB to 81dB. You need to put that 81dB SNR into perspective: 1) you won't hear the extra noise at normal volumes at normal listening position - even playing digital silence 2) if there is ANY music playing you definitely won't hear it! 3) The SNR of the best vinyl replay is <60dB, the best cassette decks managed 65dB (just), the best Pro RTR tape decks (properly aligned, with new tape!) could do 75dB... so 81dB is well higher than any of those. This is why you won't hear it. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
