Cable for lowend More Full sounding


I have a biamp situation with tube upper and solid state lower, Crossover is 200hz Von schweikert
I am using Audioquest Midnight for the lows, Well controlled but dry,Can i improve on that?

I read on another site that someone stripped their Midnight cable at the 18GA setting. That's too thin for bass duties. On my bi wire set up, I use 10GA (stranded silver) for the lows and 16GA (solid silver) for the mids and highs. The sound is fabulous compared to my old set up using jumpers. 

All the best,

Put mid-range Wireworld on the upper part.  It will let the bass come out.

Of course, room treatment will affect the sound much more than cables.
Larger conductors (heavy gauge) would do the trick, for instance Deulund 12 awg cotton in oil. Cables are inherent ton controls....
