Preamp Selection

I'm running a newly acquired set of Pass Aleph 1.2 power amps and am thinking of a new preamp as well. The obvious choice of a Pass Aleph P won't work because I need more inputs (5 + tape loop) than that preamp provides.

I'm considering a Krell KRC-HR, and an ARC LS-10.

Does anyone have experience with these two preamps?
