You may want to look at preamps by Blue Circle BC-3.1 and BC-3000. I have owned the BC-3.1 and it threw one heck of a soundstage.
Preamp with deep soundstage suggestions
I'm looking for suggestions for a preamp that throws a deep holographic soundstage. I am not as hung up on transparancy or neutrality as I am with lush, deep, imaging. Considering new or used but less than $2000. Associated equip; Graaf 50/50 power amp, Metronome CD-V1 CDP, Jamo Concert 11 speakers. Thanks, Frank
