I wasn't saying that the Muse model 200 sounded better with certain mains cables, it sounded better with a big ass dc filter or mains regeneration. No amount of passive cable swapping made on iota of difference.
I realise others may have made claims to the contrary. I was just highlighting that a shit amp cannot, ime, be fixed with fancy cables with no sound engineering basis.
I think my post you quoted was responding to rag, and yes I agree with you.
