Audioquest Chicago Interconnect Upgrade Options

I recently picked up some Audioquest Chicago interconnects to replace my BJC LC-1 interconnects and am considering getting a 2nd upgraded pair to cover my DAC and SACD player.

I think my top contenders would be the following:

Audioquest - Big Sur or Red River

Morrow - MA2 or upgrade

Kimber Kable - PBJ or upgrade

I think $200 new is pretty much the absolute top dollar and that would be a stretch as I'm very happy with the Audioquest Chicago cable that I have.

Should I just get a second cable that's the same or try something new?
