Need Opinions for Different Cable Manufacturers/Cable Designs

+1 Silversmith Fidelium speaker cables - a sonic bargain. I’d also wait for the Silversmith interconnects whenever they are released - best bang for buck sonics also.

As I write this, I just realized that Silversmith SC and IC may be my ideal choice for my flea watt tube audio chain I’m building on a tight budget. 

Again with the cable arguments, how fun those are (nope).

I've had good luck with smaller brands. Stuff like Audioquest and Kimber are fine, they make a good product but you sure pay for it. Brands I've enjoyed that are smaller seem to offer more for the money. Audio Art is a really good one, Triode Wire Lab as well. Lately I've been trying out Veritas Cables and been highly impressed with their stuff. 

I would only buy from a brand or dealer that allows pain free returns. Cables are too system and listener dependent to get stuck on something that you don't love and can't return. 

I would definitely add Silversmith Fidelium cables to your list of cables being considered.  I swapped out some very good Mogami speaker cables and replaced them with the Fidelium cables and the results were astounding. Better soundstage, improved definition, better tonal qualities of instruments improved bass.  Even my non-audiophile wife, who loves good music nonetheless, immediately noticed a radical improvement.  I also swapped out a set of Morrow Audio level 5 balanced cables for a set of balanced Fidelium interconnects and there was a noticeable improvement.  I contacts the designer/vendor of the Silversmith Fidelium cables, Jeffrey Smith, about buying a set of his cables for my two sub-woofers, and he said I would not notice much of a difference with the sub-woofers, a refreshing bit of frankness and honesty.  I am using the Fidelium speaker cables with my Fyne F-702 speakers, a Rogue Audio RP-7 tube preamp, and a pair of Odyssey Audio Kismet mono bloc amplifiers, all of with which I am extremely satisfied.
