Hi Jc,
I am glad you found the cause of the sibilance in your front end. The experience you had with the Mac MC-402 demo (bright, glaring, sibilant) was puzzling to those of use with this amp. When we change a component in the chain, we tend to look for the obvious cause and effect. In this case, the amp seemed to be the culprit. Your evaluation of the Mac may have been tainted due to another component in your system. Good luck with the new Krell amp.
