I've got a pair of RTI 12 and one week ago i've bought a marantz PM 7200 (integrated amplifaier). Wire are big ones but cheap and I'm using bi-wiring. i've got a problem:when I put music that has the high at high volume it's quite clear a little of distrortion from the tweeter, as when there is a forte with pianoforte playing with the high keys or when there are some rock guitar aggressive in the high tome of their solo.

Do you have any suggestion for this?
Thanks
