Cable Hedge

Maybe cables make a huge difference. My guess is that there's alot of other things that can go wrong more easily. But I haven't had 1st hand experience either way.

My system consists of entirely of E-Bay winnings: Adcom GFA 555 amp, PS Audio 4.6 Pre-Amp, Harmon Kardon CDR-2 and now I'm finally getting decent speakers: Meadowark Kestrel Hot Rods- so I'm now thinking of a step above Radio Shack cable.

1st the Kestrels: What will signal to the world that I'm a serious, delight my tactile sense & avoid dangerous signal loss without burning a major whole in my pocket?

Additionally, I have Infinity & Boston Acoustics bookshelves that I sometimes run off of the same system via a speaker selector (Adcom w/ circuit protection) so I can enjoy music through the entire house! (gadzooks! such an abomination!) This wire might even run maybe 20-30 feet & might even be Monster Cable or something similar. What's best? Please be specific if possible.

Finally, it'd be really cool to have some nifty but thrifty cable terminations. Where do you get those? The Kestrels are not bi-wireable. They do boast something proudly called a Cardas Post. Can anyone suggest a cable termination with an equally poetic name? And/or something that will compliment said post?

Thanks you guys! I've seriously gotten alot of good advice here. You guys rule!
