Hi Jeff!
Hows things? Havent seen you on here in a while?
I had a PV-10 for a while too.
It had great build quality, and is available for great money second hand.
I did feel it had a sonic character though, and you can get (in my view) much clearer/more detailed etc from comparably priced active pre-s.
In fact, an Audio Innovations L1 (about £250 used) is a better bet in my view. Not a very pretty pre however. It's easily improved by changing a few parts too.
I just wanted to say you don't have to ''spend the bucks'' to get (what I consider) to be a pre-amp that I would personally choose over the MF.
The Diyhifisupply Basie + Aikido (about £600 built up) I would choose over it in a heartbeat.
Julian (doesnt post so much anymore) came and visited when I had the MF up against my Basie (an older version, not as upgraded as the one I'm using now), and we both prefered the presentation of the Basie.
The source has a high output, and the power amp was set to easily take a passive - so it was a preference of sound.
**edit**
I know some people prefer passives, and above them TVC passives - and good luck to them. It's a choice of the sound that you want at the end of the day, not a ''better'' ''worse'' scenario.
