Thanks Paul,
Actually, to the extent there's a volume issue, it may be on the vinyl side. My speakers are notably inefficient (about 88 db) but that's been ok for my room set up. Even with hi-eff (Altec Valencia) I tend to max out volume pots, though with considerably more output on the Altecs.
The question really comes from curiosity about why my preamps (Don Allen gen 2 and VTA SP-14), which work quite well with their respective counterparts don't cut the mustard (i.e. aren't in the same ballpark sound-wise) with the SM2 in 'passive' mode.
These (IMHO) are pretty nice preamps, so I'm left thinking the issue must be one of matching??
Curious about others' experiences here.
Grazie,
K
