For those of you who have experience with Brent Averill's 312 preamps
(current Avedis version)... would you or would you not recommend them
as solo preamps - meaning that they'd be the main go-to preamps in a
given recording situation (primarily vocals, acoustic guitar, and other
overdubs - bass, percussion, some electric guitar)?

I'm currently using John Hardy M1's and while I like them, I'd like to
try another flavor. My M1's have the output transformers, is this "too
close" to the 312 to warrant switching? Thanks...
