I have heard the IC-70 but not an IC-50. I liked the IC-70 for waht it didon the top end, as well as it was a warmer cable than the Harmonic Tech. Silver I have. But where the IC-70 failed was low end transpareny, ie., listening to symphonic music string sectiions were shown as a mass of sound rather that individual instruments as a group. The HT while deliniating these diffrences was not as musical overall. I always wondered if the IC-70 was not broken-in enough at the time.
