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!

Bob-- Thanks. Interesting point, which I'll keep in mind. For now, my goal is to see what can be done with the current set-up. If nothing works, then I'll certainly consider changing speakers or amp.
Forget about wires, cables, footer, sorbothane, and all the other tweaks. The most important thing in a system is the room and speaker placement. Not that I'm a guru or close minded, but anyone who thinks a new power cord or speaker cables will solve an issue like bass response batter than speaker placement is an idiot.

The cables and tweaks can and do work, but not to that extent. They're worthless if everything isn't set up correctly IMO.

I know... I'm going to catch a lot of flack for that one.
If Stuartk can not move the speakers there is no reason to recommend that he do so...
"The most important thing in a system is the room and speaker placement."

Also match between amp and speakers.

The rest may help but cannot substitute for getting these two things both right first.
