Budget Strategies forTightening up Bass?


My system: Opera Consonance 120 Linear CDP, Extensively modded Jolida 302B, Silverline SR 17.5 monitors. AudioArt Speaker wire. Various IC's. Short of buying a sub, what is biggest bang-for-buck upgrade to tighten bass? Wire? PowerConditioning? ("currently" I have just an upgraded cryo-treated outlet) Better footers? (I have vibrapods and cones). I've got about $350 to spend on this... I know-- that's not much-- maybe my goal and my budget are mutually exclusive. Still, any suggestions would be appreciated!

Is your floor a suspended wood floor? Can you get under it?

If yes to both, the biggest thing you can do to improve the bass is to brace the floor.

I have two 12' long 4x4s running front to back, (13' deep room) about 5' apart, perpendicular to the joists, held up by 4 of those height-adjustable basement support posts.

I have since added a layer of 3/4" plywood on top of the original floor (w/ Green glue in between.

Everything I do the the floor makes the sound so much better. I know that I could not have the sound I do now had I not braced the floor. Absolutely essential.

See the 'nearfield listening' thread over in speakers.
Vibrapods implicated in bass issue. For better or worse?

BOB: My understanding is that Alan Yun designs his speakers with tube amplification in mind. At least I've read that somewhere-- that's not a direct quote from him.
As for the room, it's an "open plan", so the livingroom where speakers are located is separated by a half-height wall from adjacent diningroom and open to adjacent two-story entry. A pretty large space.
MICHAEL:I will look into the sub option. As for reinforcing the floor, it's hardwood, suspended. I can't see covering that with plywood.
MAGFAN: I suspect Vibrapods are not the best footer in my case-- I plan to try alternatives.
