Rbf1138: I use a pair of Vandersteen 2Wqs with my 2000s, but that's not in your budget. In your budget, I'd look into the Velodyne EQ Max 8. IMHO, having the ability to EQ the in-room response of a sub is very important, and in this price range, not many subs offer that capability. If your room is appropriately sized for the MWTs, the EQ Max 8 should be sufficient, especially for music (as opposed to home theater). As for the connection, I prefer the subs to be in-line with the main speakers, the only way the Vandys can be connected. However, it is often the case that the sub's built in high-pass filter for the speaker-level connections is inferior to the crossover in an AVR or preamp or integrated amp. If your Peachtree has an internal crossover with an RCA subwoofer output, it will probably be better than the crossover in most subwoofers. But try it both ways and see which sounds and blends better.
Finsup: Although my 2-channel signal chain does not use any room EQ, my surround signal chain does. I have a Pioneer AVR with MCACC, which works rather well, especially compared to the Audyssey built into my previous pre-pro. I have to admit that there is a "rightness" to the sound when I have even lo-res sources on, like Music Choice on FiOS. The jazz channel, which in my set up must come through the room EQ'd Pioneer AVR, sounds amazingly good for a compressed, reduced-resolution digital signal being converted to analog by a <$500 AVR. If I had more money, and was not such a die-hard analog fan, I might look into the higher end room EQ products. My main suggestion here is to insist on the ability to fine-tune the room EQ results after the device does its thing. My old pre-pro was all-or-nothing; if you didn't like the way the Audyssey EQ'd the room, your only choice was to turn the whole room EQ thing off. With the MCACC, I can fine tune it, correcting any setting I don't like, while keeping the rest.
