Not much in terms of true stand-along Pre-Pros. Most people looking for a Pre-Pro in this price range use a receiver. The Yamaha 1400 would be an excelent choice at around $550 online. A HK 325 would be another god choice. A Denon 2803 would also be a very good choice. One the lower end of the price scale look at the Pioneer D912K.
In most cases receiver manufacturers cut corners to keep costs down. Usually alot more corners are cut on amplification than processing. You would really be suprised at the processing that midlevel receivers have. Once you expand the budget up to $800 the Outlaw is pretty much the only way to go in terms of true pre-pros until you get into the $1500 range. Don't think the processing is compromised just because it's in a receiver. For example the Rotel 1055 has the EXACT same processing as the 1066 pre-pro but adds 5 channels of amplification. The 1055 also COSTS LESS than the 1066.
Okay, so what your paying for in the AV receivers is basically the quality of the amplification and NOT the quality of the processing-is that fairly accurate?
If that is the case then I'll just go for a good R with low wattage rating but with good processing.
Great advice you guys-If I come into more money unexpectedly I'll be goint the NAD t-163 route
