I was comparing Parasound 1205A with Rotel 1075. While everything else seems to be comparable on spec, the current was quite different. Although they both called theirs "high current" amps, Rotel's high current was 15amps whereas Parasound's high current was 45amps. Even if one being conservative ane the other not, it's 3 times of difference. So,... what that 45amp will bring to me which 15amp cannot? Does it make Parasound a better amp?
