Just saw a pair of Acoustic Energy Aegis EVO1 for sale on Audiogon for 195 you can check it out. These are What HiFi Speakers of the Year. They may not have the bass of the 4T but IMHO have better midrange and sweeter treble. You can play these super loud without distortion. The Nad 320BEE would be a very good match as recommended by What HiFi.
This would be a perfect 500 dollar system and I doubt you'll find a better system for the price. You may have to wait for a AM/FM radio though.
