Cable comparison charts?

mammothguy54,
Thank you sir, I appreciate that. 

And if I may....for cables that you are very interested in but can't find an avenue for home demo, try the used markets. You can find just about anything you may be interested in relatively cheap and you can always resell for little to no loss if it doesn't work out. 

I learned that one on this forum years ago and it paid off on my purchase of Acoustic Zen Hollogram II speaker cables that were basically new, but half off list. 

treynolds155, thank you for the good information.  I presently have all that I need but who knows what the future may require.  I have been exclusively using Audioquest products since 1990 and presently penetrate well up into their line for all signal, speaker, and power cables (Earth for signal, William Tell ZERO for speaker, and Tornado for power).  I personally find their methods of R&D, metalergy, application of materials, and manufacturing process to be superb and meet all of my needs.  But I do have an open mind, and especially for a great price it's always fun to try other products, too.  I will keep in mind what you mentioned.
Be safe and healthy. 

Thank you all for your informative and sometimes entertaining advice.  I value it all. 

You might miss out on a good cable looking at specs alone.

Noting your question about Cardas and specs. They release some specs on a few cables, not all. They will tell you not to listen to their cables based on specs, and to work with a dealer on it if you can. Tested many Cardas!

Some of the better local dealers and better retailers still around may let you demo them, on a charge/refund basis. And, with the anticipation you’ll follow through and buy something from them. With cables, many of us like to say to support your local dealer if you can, those who remain. Or, try TheCableCo loaner program for a fee. 

i have to say the idea of using printed specs to select a cable seems silly to me

to each their own...

...but cables' sound is probably the hardest to quantify or characterize using ’specs’

really must audition at home in the system in question, otherwise it is really a crap shoot

you may think you know... but you really don’t -- nothing replaces listening
