IC. On Jessica all that stuff is great. I haven't reached a point of that yet. On Bertha I can use her up. And real high volumes I always backed off because it was hitting what I called distortion. So IMO on Bertha she hits the wall kinda easy. But Jessica until I get bigger speaks I don't think I'll have that prob. There is a huge diff on sound between this FC and the audition amp also. I nvr hit the distortion point on it but it did lose some at extremely loud volume levels. This amp stays together at all points. It really let's this pre show itself and unleashes what my speakers were designed around.... Ask peewee . My speakers sound like a new pair from yesterday morn lol. Like I said earlier. There's no sutle diff in any dept. it is a whole new world now !!!
