More Power or use subwoofer to boost bass for music


Hi,   just want to know if anyone can offer their opinions on how to boost the bass when listening to 2 channel music.

I just got a pair of B&W 804 D3 and would like to get more bass out of the speakers.   I remember the bass was pretty punchy when I heard it in the dealer showroom, but I don't seem to get that in my setup.   I currently have Parasound A31 power amp with 250 watts per channel.

So the question is whether I should get a more power amp, or add subwoofer to my 2 channel music.  I'm a little bit of a purist and would prefer not to use a subwoofer for music, but I'm open to this option.

I would definitely appreciate if anyone can share their experience/opinion.   Thanks very much.

The moral of all this is one size doesn't fit all; in fact, the very opposite, every case is unique.  Variables, among other things: size of room, construction of room (floor, walls, ceiling); viable positions for speakers; speakers themselves, etc.  Some people will achieve excellent results with 2 subs, a happy few (?) with one.  And some may need more for "equitable" bass.  The upshot: one solution doesn't suit all.
@ erik_squires  Hi, you seem to be on a crusade to put down something which is valid and sorts out what is a real and common bass problem. I think the recommendations, for a DBA including from myself are in response to an understandable and innocent question from the OP.

By making these recommendations nobody stands to gain anything except for audiokinesis who can be commended for not relentlessly punting his product, unlike some vendors.

Casting aspersions on somebodies honesty and integrity is off-field and you need to wind your neck in on this. I think the ethos of a thread like this is to contribute in some meaningful way and not thread crap.

I've never put down the swarm on the technical claims, and your claim of my crusade is clear projection.  I've even seen fake / one time use accounts created to refute any other options beside the swarm are viable.
People can ask about FM tuners and some one will jump in to recommend the swarm as a fix.

It's not the technology, it is the cult and those who push it.

Best,

This might be a shot in the dark, but have you experimented with power cords at all?
I had a power amp that changing out the stock power cord, was like Jesus showing up in the room. (Thought I'd throw that in since we were talking about cults)
Also Schiit makes that inexpensive equalizer..
Duke and Ralph did a great job of clarifying the swarm concept and it's applications to different settings, with related options...great to get the info finally from very knowledgeable members...
