I have a REL sub that I preferred over many other subs i auditioned. For strictly music listening, I preferred the cleaner sound (faster, smoother) of the smaller woofers (10") over the larger (12"+) models. Also, REL subs produce an awesome smooth low end (down to 10hz in some models) while using these smaller drivers. REL subs are highly rated for both music and home theater applications. It is the only sub that I know of that allows both LFE and high/low level connections at the same time, with seperate gain controls for each input. I also like their "ABC" circuitry that allows you to finely tune the sub to both the room and the main speakers. The Revel is also an excellent sub.
Also, i would not purchase a sony dvd/sacd/cd player combo player if you are listening to cd's most of the time. Buy the best cd only player you can afford and you will be better off. I have a sony 9000es player for my home theater setup and use it for sacd and dvd use only, i do not like the sound of cd's thru it as well as the Classe cd only player i have in my music setup. I demoed quite a few SACD/cd (from the cheaper Sony players to the $7500 Marantz) combo players before i purchased the cd only player and I liked the better cd only players (Classe, Arcam, Naim, Meridian, etc..) over the combo players.
Good luck.
