whats the very best sounding cables for realistic money

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.

Analysis Plus.  Their "bottom of the line" interconnects and speaker cables are great.  The mid-priced ones are excellent!  I've never felt the need to even try their "top-of-the-line."
