How can mains cables change anything? Assuming you're not getting a lot of electrical noise.
Thicker core with shielded cable. Bigger amps require a steady supply. I’m not fully into the mechanics of how and why, I’ll be perfectly honest.
You get guys who only believe what the testing equipment says and there is no way it can be any different. The science doesn’t lie kinda guys.
Until you sit there and actually have a few amps or cables to listen with it is hard to portray what you want to say. Music is an emotion. Equipment doesn’t measure emotions. Some people have no idea about transients, decay, bloom, imaging etc. I’m not fully into the hi-fi speak as it actually sounds quite snobbish and boring if I’m truthful. What you would want to say as to how the soundstage is would be different to how I portray it probably. Does buying more expensive gear return a better overall quality of sound. I think it does.how far you go up that ladder is up to you, the wife and your wallet.
Most audiophiles who buy this top end gear are retired and old . The irony is their hearing isn’t what it was. They only listen to composers and string quartets and such.
Try going to a hi fi show. They play the same stuff all the time. A great master copy of some music that doesn’t test the system at all.
Although a nice piano piece does make you sit up and listen. With some gear the notes just hang in the air. It’s quite palpable.
I can sit there in my lounge, no dedicated listening room and pick out exactly where the musicians are, where there instruments are. Which side of the mic the singer is. This is what a decent set up will do for you.
Sometimes you could reach out and touch the singer, they feel like they are in the room with you.
I believe there is a level bs and said snake oil that perpetuates the lambasting the nay sayers give the audiophiles. It will always be there. does it bother me? Not at all. Do I wish I was knowledgable so I could put them in their place. Nope, I’d rather listen to my hi-fi and let the debate carry on.
I say let they guys with the money keep buying the latest gear that is pushed on them. I can have their hand me downs.
The system I had five years ago started of with kef r500 speakers an audio research vs115 tube amp, a Bricasti M1 dac, a pc that I built, Sotm 200 ultra USB clock, power supply and server. kubala sosna emotion cable. I then swapped the kefs for a pair of Sonus Faber Olympica iii’s.
The speakers were too big for the room, knew it as soon as I got them. I couldn’t get on with the digital sound of the dac or the streaming. So it all went after about 18 months apart from the amp.
It’s all part of the journey I guess. I am pretty much done with what it have now. Maybe I’ll diip my toe back into The digital side.....who knows.
