I've been on the cable merry-go-round for a very long time. To me one of the very best lines is Audioquest. You can determine easily what each model uses for conductor material, geometry and insulation materials, etc. Basically the price goes up as the conductor quality goes up. Go to their website and open their Pricebook tab and then scroll to product categories and study a bit. There is no mystery as to what you're buying. IMO the all copper sweet spot is perhaps Yukon interconnects( $325 m)and Rocker 88 speaker cables($ 850 8' pr) . Both models are AQ's least expensive models utilizing their best copper. As you move up you get maybe better insulation materials and more conductor, etc , but the basic construction and geometry stay the same. Once you start up the silver models the cost increases significantly but the sonics are outstanding but still in the same family. Packaging and cable construction is all top notch,
The only problem with Audioquest is that they've been successful for a very long time thus making them 'conventional' to some audiophiles. I have to say in closing they are the best company I've used that is reasonable about reterm and unfailingly polite and professional. To me searching for a mysterious cable breakthrough is folly. AQ offers solid engineering with no voodoo.
Finally it is very possible to buy higher end AQ cables at great pricing as long as the buyer is cautious about the seller. FWIW
