Stephen, I've read your other posts as well and it seems to me you're focussing too much on the bass. Any system of quality can achieve 'bass' simply by 'turning up the bass' and this can sound out of balance. If you really want bass more than the rest

rather look at a pair of Cervin Vega's and a Studio/Pro amp like Behringer. If you want good quality HC then any of the respected brands will suffice. My personal reccomendation to you would be (and i'm combining your other threads here)
AVR - Yamaha 4600/2600
DVD - Pick you poison here but a Denon 1920 is good buy IMO
Speaker package : Monitor Audio Silver (Good bass), Kef iQ series
Sub : BK Monolith, SVS PBxx
