musical sub


I need to improve my system with a compatible sub for my system as it has evolved so far. My primary concern is the musicality, although Home Theatre is important, it is not as important as the music enjoyment. We watch a lot of music dvd's and play lots and lots of CD's, and of course third is the home theatre.

For reference, the main pieces of my system so far are:

McCormack HT5 amp (5 channel)
Anthem D2 processor w/ Arc
B&W Nautilus series 804 fronts, HT2 ctr, SCM surrounds
McCormack UDP1 disk player (the upgraded model)
Dennon 3800BDI blu ray player
etc.

What I am looking for is something that will add to the system, is very musical, and that will survive eventual component upgrades as I learn more and refine the sound.

Any suggestions on the sub? (or equipment)

Thanks

Adding a sub to your system will not deliver the musicality you seek, you'll just have more bass.

This statement in most cases is correct.
If he adds a Vandersteen 2WQ with High pass his system will have a tighter bass smoother in room response with across the board better definition.

Two or more subwoofers is a good idea versus a single of higher quality. Martin Logan has some good fast and musical subs.
Audioconnection,

I think I understand the point you are making (that if he chooses a 2Wq rather than some other options, it would make it musical). I disagree. Although that is a fantastic sub, I am quite sure that still_learning is dealing with the artifacts of not only lean bass but also harshness, brightness, and bland midrange. Adding a sub may mask some of this in the short-run, but in the long run will still only provide a frustratingly un-musical listening experience. IMHO.
Maneiac your statement of: "artifacts of not only lean bass but also harshness, brightness, and bland midrange",
must come from your opinions of the components. What are your specific concerns and what would you suggest to correct it / them?
