Preamp with bypass/throughput


Hi all,
I've been browsing the classifieds for a couple weeks now looking for a good stereo/dual monaural preamp (~$1000 budget) with a bypass feature. I haven't had any luck keeping my eye out... are there any suggestions on what I should be after?

The Emotiva XSP-1 balanced differential preamp has gotten some favorable reviews. And it has HT bypass + a 5-year warranty:

There should be lots of options with either an HT bypass or Tape monitor capability. But these features may not be mentioned in the ads.
You might look for a used Cambridge Audio 840E either here or on eBay. Should be less than $1000, great sound, highly versatile, and a pass-through.
