Scottsman,
There was no problem with the front end or cables when I listened to Rowland and Mac autoformer amps on the same systems. Some people prefer the Rowland sound, IME. I'm not one of them and simply report why and what I hear. And what I describe has been consistent with Rowland in any combination of gear I've heard them in. They carry a distinct signature that apparently resonates with some folks. It is a clean, analytical, clinical sound that works for some. Rowland amplification to me, whether ICE or normal topology, hasn't risen above hifi sound and has lacked tone evident in the acoustics of real instruments. But its sins are of more of omission than commission, to my ears. That is, they do not introduce fatigue factors or obvious distortions. In the overall scheme of things, good amps well made. Compared to Mac autoformer amps, not in the same league by my evaluation.
