I have been shopping for a new tonearm cable, and also learning along the way. In a tonearm cable, the cable is real subcepible to low frequency (motor) what silver audio people explained to me it has everything to do w/ sheilding of the signal wire.A regular IC may not have the same sheilding to get rid of low frequency. So tonearm ICS differ from source componants ICS in the sheilding of the signal wire. And then you need to consider the composition and design of the signal wire also. David
