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!

I've found that sorbothane under a CDP makes the bass 'riper', while inverted brass cones make it 'tighter'.

your mileage may vary...

you might also look into a DAC. the different flavors of D to A vary enormously between brands (e.g. theta = kind of gutsy while sony = analogue-y). you'd have to audition them in your system to see if that addresses the problem.
try a VenHaus DIY PC <$100 ea

you may realize other benefits as well

power cords make a big difference and may be all you need
Speaker cable and power cords. A good power cord will tighten things up - 'A LOT'.
Just a guess, but I have never had much luck putting speakers near any walls, not to mention corners.

If you want to use the room as a tone control of sorts, often better to bring the speakers out from the walls, and push the back of your listening chair against the wall.

Still guessing, but I would think this would also dramatically improve the imaging of your Silverline speakers.

Not sure how this might complicate your decorating, but you asked about tightening up the bass, not your marriage.

Good luck.
