Utter nonsense. We're not in the age of valves and analogue synthesizers.
What next... Directional copper cables? Audiophile Ethernet cables for a superior sound stage?Audiophile grade capacitors, for a warmer, more 'chocolatey' experience? £50k kettle leads?
Vacuum tubes, VFETs, Class A FETs all sound very good, better than a traditional solid state Class AB. Ncore does sound very good too, but they are a completely different animal.
Directional cables make sense because they prevent a ground loop. They ground the shield at the source, not the destination. So, yes, they can make a difference ( most of my interconnects are directional).
Ethernet audiophile cables, I agree with you. They're up there with the Tice Clock, but they sure look pretty. My solution is to get good Cat6 cables and dress the with a pretty cover. Red silk looks very nice. My favorite is the audiophile Ethernet switch. Now that's brilliant... a brilliant way to take money from audiophiles. What next? An Ethernet router optimized for HDMI-4?
Audiophile grade caps.... look, I put those teflon caps in my CJ preamp. My wife says that now we listen to music, not a "stereo". So listen before you criticize.
I'm surprised though that you failed to critizice my latest discovery: mercury troughs for speaker cables. Sure, vertical elevation is a challenge... but the sound is so much more liquid than before. Flip side is that we have to use respirators around the house, so that might contribute to how everything sounds different now ( "Hey, what? What did you say? I can't hear you.." ;-) )
