Gotta agree regarding possible wire/cables.When I first read the OP topic it immediately reminded me of my experience with wires in particular-
I did a XO upgrade on my 1.6's many years ago and I decided to go cheap route and purchased a spool of regular red wire from Radio shack. The moment I fired up my system the harshness hit me to the point I thought someone had swapped out my Jeff Rowland amp with a MCS amp from JC Penny. Funny thing is I knew it had to be the wires so I removed them and used the original stock wires and the harshness went away. I then ordered a spool of teflon coated 999.9% pure silver (not silver coated!) wire and the results were astounding, and I never looked back from that point on.
And yes although the original post has nothing to do with XO wiring, I'm a firm believer that Maggies will reveal short comings -or more specific- 'incompatibility' of different cables.
I would recommend the OP borrow a different set of cables or even purchase another set (doesn't have to be ultra-high end; heck even Amazon so you can return them if no difference is noted) to eliminate them as the source of distortion. This experiment would be cheap (compared to swapping out amps) and would eliminate a lot of potential headaches.
I personally build my own interconnects but have on occasion used 'bargain cables' to demonstrate A-B comparisons.
Good luck in any event-
