Thanks for all of the responses on this thread as well as the speaker thread. It sounds perfect now! I'm very content with anything I throw at the system.
@Oranfoster, I love the XX-2. It will be the last thing I change in the system. It's ruler flat top to bottom and coupled with the JC-3+ sounds like you are in the recording studio at the live performance. Make sure you spend some time getting it precisely mounted. The stylus is L-O-N-G, so it's easy to see when you are using a protractor to set it up. I used the Mint.
I may do the low plant thing temporarily! I'm building an equipment rack specifically to hold everything nice and tidy, mounted on the wall. I had to mount everything to the wall to kill the feedback loops that were being transferred through the floor. Everything is dead quiet now. The rack in the picture used to be on the floor in front of (and hiding) the rat's nest of wires.
