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 ??????????

Yes - concur with Anti-Cables as great cables for the price.  

Though, I've also made my own anti-cables speaker cables 
, using magnet wire purchased on Amazon - very economical, and sound about the same.

Cerious is fine price/quality - River Cable Flexigy8 is to me the best value around for an amazing speaker cable - Coincident Statement Power Cord for power - Best signal and best speakers cables I ever heard out of dozens I tried, including much more expensive ones, is TelluriumQ SD.
