Is my amp the problem?

oh, I got it. You have to be a member and logged into the forum before they will show you the listings in "The Emporium" section.

Bingo :)

BTW I see a parasound 2125 for $340. 150wpc. a little bit newer that the hca series and still cheap. 35amp and 33k input imp.

I've never had great let alone decent results bi-amping my speakers even using 4 channels out of 5 on my audio refinement multi 5 amp. I do bi wire all on the speaker end with Tekton 6.5t monitors in the past and currently ProAc Studio 148 mini towers. 

OK so today I got some improvements. I got the good caps from Modwright and installed in my KAW 100SE. That sings sweet now. I had the woofer amp plugged into a power conditioner, I plugged them directly into the wall. I worked with the Xo points/slopes and now it's beginning to sound much better. Not perfect but it has come a long way. Now i still have some caps Dan sent me to install on the LS100 that he says will improve the bass response. I'll do that tomorrow.
Stay tuned :)

Caps installed. deeper low end response. PLayiing with Xo for best Xo point.
