Hi joepro,
I don't recall any figures on that. The PM-1.5t has a change of sensitivity during it's production run. Early units were 3.0 V for rated power and that changed to 1.5 V. So the gain was 26 dB, then 32 dB. The 32 dB figure was common for most consumer models. I find that a little high.

Hi joepro,
Most amps run around 30 dB worth of gain, + or - a few dB. It isn't that critical. The exceptions are those "fantastic" amps cobbled together in someone's basement or some low production quantity amps where they don't adhere to any standards. Chasing perfection.
Consider this one point. In 5 years you may have the same preamp (or not). What amp might you have then?
So relax and get one as close to normal as possible. There is no such thing as perfect anyhow.
