Guddai from under your left foot!
I like both of the previous posts. I LOVE tweaking but,mostly, I keep it reversible. Tweaking is my second pleasure to listening to music. Tweaking is the reason I love klipsch. IMHO klipsh should not be bought by folk who are just going to plonk them in the corners and expect them to 'do it'.
I am a cheap charlie who loves to tweak for a modest outlay, so, here hear to Charlie. Wire mods from some companies are for the sole domain of the Sheik of Brunei.
Back to mobile homeless , I also like solid core.The thinner the better according to its current. My loudspeaker wiring is done with silver coated copper, teflon coated, about 24 gauge. Long time back, i bought some Apature speaker cable to use as an interconnect . Cheap Charlies discard wives but not paraphinalia. I stipped the multitwisted cable and separated out the numerous single cores. It became rather good value then.
I have rewired the crossover with solid core too. My speaker cable is 1 metre of Audioquest Midnight
