Atlas cables are pretty good as a breed as I remember, but I must advise that they exist purely due to a group of retailers buying in bulk (Mountain Snow, IIRC) and making shedloads of profit on each one they sell.
I found Soundstable on eBay very helpful and he uses decent wires and connectors. What isn't in his shop can be made up to order and when I pleaded poverty and asked for some pro-patch mic cable to go with the neutric phono plugs I ordered, he added 3m and charged me a very nominal amount extra (bearing in mind he has to buy 100m drums at around 70p per metre). great service I think and the wire sounds good as a turntable to amp wire as well....
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
