Best pre-amp w/ HT pass thru

My Krell HTS has a few annoying attributes, and I'm tired of compromising my stereo audio for my "almost" as important Home Theatre. Anyway, digital pre-pro's (without analog bypass) wed you to a point on the everchanging DAC technology curve. So I'd like to go to an analog pre-amp w/ HT pass thru and a separate HT processor.

Eagerly looking for suggestions on a good pre w/ HT pass thru to mate with my Krell KSA-200S and my Martin Logan SL3s. My target is ~$1000 used on current market. I would consider tubes, but frankly I'm real concerned about getting into the requisite tube-replacement cycles.

THANKS!!
