Yeah, saw those. I'm passing on the MoFi preamp for now. I've read it doesnt always pair well with Rega turntables because they lack external ground wires. Hums.
$450. Very intrigued by the Project Tube S2. Looks like it can handle both MC and MM carts, plenty of adjustable gain settings, sub filter, and removable tubes. Also like the small size, so I can tuck it in between my components. Seems like one of the few affordable tube preamps that isn't just garbage.
Also, it used to sell for $399. Now it's S450 everywhere. So, my frugal side demands I find it for $400 or less.
