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 ??????????

I had some PWB Electronics speaker cables along with TG Audio speaker cables for my bi wired Fultons. The PWB cables are very good and quite exotic but affordable. Dunno if they still sell cables but they might.

Townshend Fractal f1 arrived yesterday and I was shocked by its performance, did not expect such a great improvment in all areas. Furutech Evolution II is garbage compare to this ultra higend cables for such a little money. Highly recommended!
Agree with f1 fractals: I got f1 fractal XLR ICs today and right out of box, they are wonderful. They do good in everything. I am now trying multiple cables in my system to get best, and so far this has been in the top, and more importantly the least expensive of all that I have tried. 
At the price point that the OP is inquiring about, IMO the Black Cat Coppertone's are probably impossible to beat.
