Thanks Sean and Zaikesman! Both of you seem to be a rich source of audio information. I'm sure I'll continue to be educated by reading your various posts.
Gain stage, advantages/disadvantages
I've got a Pass x-1 preamp which has a low and high gain option. It's connected to a pass x350 amp. What purpose does the gain stage serve and what are the advantages/disadvantages to either one? I'm sure this is a novice question but I'm fairly new to audio. Thanks!
