Scott - I purchased a Simaudio Moon LP5.3RS a while back.and haven't looked back.
This model is now discontinued, but the new 310LP is basically the very same unit - it just has a new faceplate.
It seems to fit your requirements very well and really benefits from using a quality power cable.
There is a separate power supply, but they are expensive and the quality power cable seems to provide similar benefits.
It is very quiet - with the amp at full volume I get a very slight hiss
The only drawback - you do have to remove the cover to set the jumpers - not very elegant - but very effective
I'm using it with a Soundsmith modified Denon DL103 moving coil cartridge on an Audiomods Series three arm and the details are superb.
The Sutherland and the Whest were also on my list, and I also tried the LFD, but the Moon performed better on my system.
Hope that assists you in your decision making process :-)
Regards...
