Thanks for all the info / comments everyone.

Mojo: can you shed a bit more light regarding the possible clipping. I don't know how else to measure this other than what I have already done. In regards to the Sherwood amps; I think at this point they are handling what I am asking them to do, but I am aware that I am pushing them near to their design limits. I am currently using 2 amps, one dedicated for the lf portion, and the other for the hf portion and the centre channel. If you can suggest taking measurements with different equipment, I am all ears.

Thanks again everyone for all of your time and support.
Have a great evening.
