Elizabeth got it right. I find it difficult to switch from albums to CD's (and vice versa) in one listening session. The first source always sounds better than the second one.
Switching preamps in and out
I have three reference preamps in house. I need to decide on which one I like best. My question is: Do I need to power preamp,source and amp off before switching IC's to the next preamp? Is there a more efficient/faster way without putting any components in danger?
