Why should a cable have to make such a significant difference and cost so much to boot
Have experienced this and, as a diyer, it's VERY frustrating!
For the 1st part, obviously the transfer function and noise reflection/rejection -- why/how? I don't really know, wish an RF person could chip in here...
For the second part (the cost), well... two points: a) small proprietary wire runs are VERY expensive
b) when a cable geometry WORKS WELL (remember, a rca cable is asymmetric, so more complicated) one just indexes the prices vs other outrageously priced products.
I'm trying to work out the Valhalla. I still have a way to go...:)
