Something doesn't seem right about this...

Hi Bruce,

Those are all reasonable numbers, and unlikely to account for any sonic differences that may exist among those cables, or between any of them and the majority of other cables.

The most notable spec difference between the three cables is their rated bandwidth, those numbers being 50, 150, and 300 kHz respectively (for response within +/- 0.5 db). Whether each of those numbers would result in sonics that are better, worse, or the same as the others is a function of many system dependent variables, and conceivably also on the RFI environment, meaning that the answer is unpredictable IMO.

Best,

Thanks Al. In a somewhat difference context, your comment about the possible impact of speaker cables on RFI reminds me about our earlier posts that we traded about the Spatial Computers Velocity Bridge (VB1). As it turns out, it was an extremely expensive RC circuit.

For reasons still unknown to me, inserting the VB1 in the amp/speaker circuit in parallel resulted in an unpleasant brightening of the acoustic presentation, almost to the point of being grainy and fatiguing. The VB1 was supposed to filter out ultra-high frequency RFI and thereby improve the sound, ... which as just stated, at least to my sorry-old ears, it did not.

Back to the cables. I surmise that as one climbs up the Kimber ladder, with the PR grade (made of copper) being the lowest rung and the TC grade (made of hyper, super-duper, ultra pure copper) being the highest rung, the price would correlatively increase. I haven't gone down "cable lane" yet, and have no present intention of doing so. That said, if I spent a heck of a lot more for speaker cables touted as being made of hyper, ultra, super duper pure copper that resulted in no cognizable improvement in sound, I could easily see myself going "plaid" ala Space Balls.

Thanks for the reality check.

Actually; Kimber's Varistrand Silver, in the Select series, would be their top rung for conductors. The Select cables(KS-3038 or 6068, "plaid" if you will) do represent a marked increase in audible performance(realism), in a resolving system.

Rodman ..., checked out the Kimber Select cables, but I didn't see the specs. Did I blink or a specs listed elsewhere on the web site?

Hi, Mr Bi- Nope; you missed nothing. Your last post mentioned a, "cognizable improvement in sound", as a factor. It was on that basis that I mentioned the Selects as the higher Kimber rungs(plaids). I've always based my cable choices on their presentations, the closest to live music being the most preferable. To tell the truth; I can't remember ever paying more than a passing attention to specs, in recent years. Happy listening!
