bache129 posts07-16-2018 6:51am@honashagen you ask question , the answer is very simpleVery true bache, the best preamp is no preamp if you can do it, with the source having it"s own digital domain volume control.
Absolutely no difference how much money you can spend , the pre amplifier -is device can change the sound in only one side- make sound worse. The ideal preamp just no change the sound quality
But the trouble is a digital volume control in the source will start to "bit strip" (loose resolution) below 75% of full up, if you have to use it below 75% (because it’s too loud) then your next best to no preamp, is to leave it up full. And then use a passive volume control after the source, this way you retain all the resolution and most of the advantage of no active preamp in the signal path.
