The bose certainly aren't high-end (or high fidelity-a distinction that needs to be made sometimes) as most stated (me earlier too). To clarify, craigklomparens is right and I would agree don't even buy high-end cables. Even if the tweako wires actually do make an improvement in the sound, its for no magical reasons, and your money (say $200 in wire) would have been better spent on the electronics or speakers from the start, where you would get far better gains. I don't pay much attention to Krell, other than they tend to be pricey solid-state class A. I don't necessarily think the Krell is a bad piece, you could have done worse. Although you probably could have found a better piece for the money (maybe the Van Alstine, I own'em too), I'd still keep it, don't go selling everything-you do need to enjoy some music. But the bose really is the weakest link. If you're ever so diy inclined a nice pair of kit speakers would perform far better than any commercial offering at that price and on par with many at twice the price. The jupiter from zalytron.com has always had my fancy for awhile, nice Raven R-2 tweeter with an 8" cabasse driver for a bit under a grand. The jaguar II from audioc.com looks promising too. Or the borealis from northcreekmusic.com would look really nice with your Krell, only $700-$1000pr. But any nice 2 way design, like some mentioned before would give you the most for your money for under a grand, or even two grand (although thier might be a three way in there worth going for) and certianly beat the bose. Using the bose for surrounds isn't a bad idea--if you're going to have surrounds. If not, just sell'em and use the money for a better set of speakers and be happy. However, there isn't a single scientific argument after 20 years that justify's any of these high-end cables. And many of their audible differences, if any, can be traced to the placebo effect or a severe amount of load sensitivity the electronics themselves may exhibit, something that's cured by better gear than cable's with your money. Audio Advisor has some basic 14 gauge speaker wire for about $.20 a foot, put the rest in the speakers. For never ending ramblings, ventings and discourse on the subject of audio cables (with some facts), spend an evening with the "on cable nonsense" thread here on audiogon that is probably over 200 posts long now.
