whats the very best sounding cables for realistic money

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 ??????????
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. 
Just pointing out this is a 3 1/2 year old thread. No doubt the OP has made his decision.
It's amazing how all the cable dealers jump you over for your wallet.
Power cord: Save the money, use a kettle power cord sales for 1-3gbp.
Interconnects: Go XLR if you have the interface on your gear. DIY is fine, a nice Audio Technica Mic cable and Nutrik connectors will be the best.
Speaker cables: it doesn't go by the pound, but by the Amp;s DF and length.
Tell me the data and I'll calculate it for you.
Than go DIY for a cable with banana plugs and save the the money.
Your biggest problem is how to spend good gbp left over from the vultures trying to rip you off.
