whats the very best sounding cables for realistic money

Morrow Audio, Signal Cable, or Take Five Audio. 

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.
