Speaker cables which bring out more bass?

Well, when I switched from Canare Star Quad 4S11 biwires to Audioparts Mas Hybrid Signature biwires, the midbass improvement was the biggest difference. FWIW, here's a link to my review of them:

Mas Signature Speaker Cable Review

It should be pointed out that these would probably be considered by many on this site to be "entry level" cables. I really like them a lot, however, and several other Audiogon members do, too.

The best speaker cables for bass I've heard are made by Virtual Dynamics. They come in a wide variety of price points and are not inexpensive, but they sure let the sound through, comparable to a live performance.

Hope this helps.

I find monocrystal cables have similar sonic attributes, so maybe you can look into cables made from monocrystal copper.
