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

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?

I agree with You. Good sound comes from source, amplification,
main speakers. Sub just gives more bass. If set up properly
bass could be good. If not it's just annoying noise.
Maybe I should explain my unique and probably not common version of "musical". I completely appreciate the tube versus digital sound distinctions. With all due respect for that issue, I may be looking for something that is somewhat halfway between both worlds.

I and my sons are guitar players. As such, I want the details and clarity and the nuances for each instrument that digital gives, but I also love and appreciate the warmth that often makes the performance and voicing more musical and avoids the listener fatigue problems. We watch a lot of music DVD's (some Blu Ray) and get to carefully watch the musicians in action and pick up tecniques and licks. I have heard musical tube systems that are warm but muddy without the detail, and digital systems with details galore but a shrill sound without soul; so neither of those fits me personally.

We have quite a few tube and non tube guitar amps, and each one is fine for their own purposes. I love my favorite tube guitar amp and it is my primary amp, but the digital ones are quite good also and I use them too. I know more about those components than I do about the high end audio equipment that many of you have obviously mastered.

I appreciate all of the advice here and am looking to learn from those who know more and have already gone through this. It is also nice to see this without the blogging wars some sites have.

Thanks and any advice is appreciated. You can see by my name here how I view myself in this arena.

When I started I may have bought some components I would not have chosen now. Time can correct that.
