On a related theme, I use Audioquest Copperhead interconnects between my CDP and amp (Marantz SA7001-KI and Sansui AU-717). This cable costs about £60 here's what it looks like:-
Last weekend, I popped into a computer shop in Edinburgh and saw an RCA phono cable branded as "AV Gear", 2m long, and it looks like this:-

and here's the spec for this cable:-
"Cable Specifications
Inner conductor: Bare copper 10 x 0.1mm (x1)
Insulation: PE ID = 3.0mm (x1)
Shield 1: Aluminium polyester foil (x1)
Shield 2: Bare copper spiral shield 32 x 0.10mm (x1)
Jacket: PVC OD = 6.0 x 12.0mm
Connector: Gold plated
Colour: Blue"
This cable costs £6.95 (or it did in the shop). I swapped this one in for the Audioquest. There is no difference. None. Not one audible trait changes. This costs £7, the AQ around £60-65 depending on where you buy. There's no deterioration in the sound quality; no less "air", "pace", "rhythm", or anything else.
So, either the guys at AV are massively underpricing their cable, they're optimising the price on the back of bulk sales to the technology sector rather than the mug's game that is the audio one, or Audioquest have chanced their arm.
