What HiFi used to cater for the general market leaving the "high end" nonsense to the likes of HFN & RR. They should get back there.
No amount of verbal diarrhoea will change the fact that even cable manufacturers need to stick to the laws of physics , not marketing pseudo science garbage.
A cable has R, C and L. Period. It doesn't have a "sound"....a good multistrand low impedance cable does the job.
I've said it before...I"ll say it again! If changing your cable changes the "sound" it either means the amp is rubbish or the fancy cable is causing instability.
My qualification to comment? Been involved in sound reproduction, live studio and home since the 70's...
