Would you change your amp selection knowing...?

@williewonka

Thanks for taking time to reply. No need to apologize for the length. Appreciate your efforts to be thorough. Still digesting, though on the initial read-through you've provided worthwhile elaboration on BJC's comments.  Performance not simply a function of conductivity as influenced by gauge, but metallurgy, and geometry too.  I think your idea of separating to reduce locally generated "intra cable" interference is practiced by mftrs. producing "flat" cables like Wireworld and Mapleshade (others too, no doubt).  Thanks again.  

I tend to agree with anhwy61, shadome, almarg and others that feel there is no reason for high capacitance in a cable. To Al's statement "A cable having extreme and/or unusual parameters would be a non-starter for me" - I say "DITTO". The amps mentioned in the OP are neither cheep nor poorly designed. Over the years, I've come to the conclusion that the three main attributes of good cables is: high conductivity, low capacitance and low inductance. Beyond that, IMO, there are a lot of very expensive gimmicks out there that do nothing more than alter or degrade the the original signal. Signal loss and degradation is also the reason that high capacitance cables do not work for high speed data processing....Jim

 Thanks for starting this thread-I had no idea that this was a potential issue with my system!   I completely agree with @elizabeth  that it is both the amp and cable manufactures’ responsibility to warn the public if there is a potential issue with their product.

 Unfortunately, much of the electrical discussion I find to be extremely dense.  It would be a great service to the audio community if someone would provide a layman’s rule of thumb for determining whether their system may be  subject to harmful isolation to to  a poor match between amp and cables. 

@cheeg While I’m not an expert by any means, I have been an audio enthusiast for more than 35 years and have had the opportunity of owning or extensively auditioning some very nice equipment - speakers, amps, cables and accessories - some combinations working very well together and some not. Regarding cables, IMO that there is little to no reason to use high capacitance cables for any system, regardless of speakers and whether powering with a ss amp (particularly a high currant ss amp) or tubes. I have one set of low capacitance, highly conductive (individual strands of polyethylene insulated Oxy free pure copper)) cables, that I now use always, regardless of what I trade in and out of my system, knowing that they will allow me to hear subtle differences in everything else without adding a character or coloration of their own. I have no worries of them raising havoc with any of my high currant amps and they work equally well with tubes. My RCA interconnect cables are short run, low C pure silver and I have no desire to change them either.....just some thoughts...Jim
