I have a Harmon Kardon Citation preamp and tuner (the model numbers are 21, 23, or 25...I forget which and I'm at work). The preamp is remote controlled and has a ton of useful features. It's not the MOST transparent (compared to my Pass), but it does sound good and it's very well made (it was around $900 new in the early 90s). The tuner is also very well made and it sounds great. Both units stacked are probably the same height as one normal preamp (5"-6" high). I'm pretty sure that I'm going to be selling them, but I haven't done any pricing yet. Let me know if you're interested and I can give you more details.
With the exception of the above, I haven't had any experience with other pre/tuner combos in that price range.
