I tried the zobels and in my opinion they worked very well.
first of all clarity and detail are extremely noticeable. before the zobel there was a slight smearing in the treble and the midrange that is virtualy gone now. also i was suprised how much better the bass got very tight and musical. We did one speaker at a time so we could AB there was no doubt the zobeled one was better. One thing to keep in mind if you want to try this. The parts cost very little about $30.00 and if they don't work for you you can just remove them. Once again thank's for all your input!
