Call me impatient, but I went ahead and picked one up (it's on the way).
It may turn out to be just as Bdgregory states: unremarkable. I just need something to amplify the cart and give me line level gain (i.e. I've got no pre-amp, period).
I mean, the thing is a head-amp, it has a volume knob for line-level gain, a rumble-filter (should you need it), a mute button, and heck, it's tube driven, so I figure for $200 you really can't go wrong.
Anyhow, thanks for the comments and suggestions - I appreciate it.
