whats the very best sounding cables for realistic money


hi,
can you all please tell me if there are a really special sounding cable out there for realistic money, ie power cables 300/400gbp, signal cables 1m 400/500gbp and speaker cables for around 600/700gbp, i know its still alot of money but there must be a manufacturer out there thats not pulling our trousers down, or spending time and money on R&D to solve problems that do not need addressing ie over the top shielding or some other marketing nonsense, the company i am showing interest in are Anti cables ??????????

+1 on the Clear Day for speaker cables.  For the money the Double Shotguns were pretty great in my system biwiring some Vandy Quatro's from a VAC Phi 200.
+1 more for Clear Day, since you mentioned "realistic". Recommend their speaker cables and ICs (RCA and XLRs).
