Can cables of any cost and quality provide bass response missing in my B&W speakers?


I'm sure variants of this question have been offered previously, but let me ask in light of the following:  I have a very modest main system powered by an Adcom 555II amp, Adcom GFP-750 pre-amp, and run into a pair of B&W CM-4 speakers (6.5in woofer, 6.5in. woofer/mid. and tweeter, and bi-wireable).  Any music with a moderate-to- heavy bass component (organ, bass fiddle, etc) just doesn't translate to my ear.  I'm using a mid-range pair of Monster cables, and in fact tried a second pair of Z-Series to no audible difference.  On the other hand I have a legacy pair of a/d/s 1090L tower speakers (2x7.5in woofers, 6in. mid-range, tweeter) that deliver thundering bass when needed regardless of cabling used, and powered by the same system.  Even tried passive bi-amping for the B&Ws by using an old Carver M-500t amp for HF input, and Adcom amp for LF input...no diff.  Is there any point really in looking at higher-end speaker wire of, e.g., thicker gauge, or exotic geometry, or multi-conductor "shotgunning", whatever, in order to induce greater LF response from the CM-4s?  Thanks for your patience.

There’s an outfit called KnuKonceptz that sell a Kimber VS-series knockoff called “Krux cable”:  2x8 18awg braided conductors @ 8awg +/- and selling as raw cable for $5.49/ft.  A 12awg braided version per Kimble 4-VS also available @ $3.25/ft.
Also, an Ebay seller called Maze Audio sells paired “litz” speaker cable (poss. 9awg equivalent, not specified in ad), 9ft., terminated, for $240.
Speaker cable, power cords and interconnect cable can very definitely make a difference as to the issue you mention!

High Fidelity Cables (HFC) has various products that I would highly recommend. I have their Reveal line of cables to include RCA, XLR, and power cable. Each product significantly benefited my system. Surprisingly, you may want to start with their MC-0.5 power conditioner. My first experience with HFC was with the MC-0.5 - it increased clarity, fullness, depth and soundstage presence.
