From my experience, I would try the K400 first. It is really fantastic for the price and works better with Linn equipment than many far more expensive cables.
speaker cables recommendations
I am looking for speaker cables and really have no idea what to get. My only thought is that price may give some indication. My system is Linn Majik integrated amp, Linn Ikemi cd player, and B & W cdm 7nt speakers. I thought I would spend about $40-50 per meter. Perhaps Linn k400 would be good? The guy in the shop where I am recomended cheaper Ortofon or Monster cables. Would anybody have any recomendations?
