Brian,
You are now entering a world of snake oil and the like. Some home made cables are rubbish and some are very good, to whit Greg used a TNT cable consisting of stands of cat 5 network cable, which he swore was the cats whiskers but someone else tried this same cable on a Naim amp and it was goodbye output transistors. As I keep telling customers "nirvana doesn't exist"
There are lots of good basic cables out there without paying a fortune and you certainly don't need to get dragged into the "Well it cost £6000 so it must be better" disease. My usual answer to that comment is "define better" Often met with a blank stare
You will need to "cut the coat etc" There are lots of cables I would like to try but as my cable run is 11 Metres and I biwire that is goodbye to 44 Metres! Even the so called affordable L/S cables at £200/metre would equal £8800. I think not!
