If you've read my recent posts on using slugs instead of fuses, then you may recall that I've been experimenting with metals less used in audio applications. To this end, I'm considering trying molybdenum, titanium, and niobium wire. The latter two are fairly cheap but the moly is pricey. Also, I don't see any of these wires offered in bundles as typical of speaker cable thus, I'll be using solid core and, in my experience, solid core actually sounds at least as good as stranded wire.
Without using spades or bananas, the binding posts on the Red Dragon amps are a PITA, and wrapping the wire around the post would seem to offer the tightest connection without possibly stripping the threads (which I've done). I'm obviously not much of a DIY guy and just wanted to make sure I wasn't going wire the speakers up in a compromised or possibly damaging way. I appreciate the information all have given. Now to go on an exotic metals shopping spree......
