Howdy 76doublebass,
It's great to hear that your ZCD is working so well ..... 8-)
I feel the same way about mine. It's interesting for me to hear your experiences with the ZCD since the speakers I'm running now are the "little brothers" of your Parker Audio 95 Signatures :

I am getting a mind blowing soundstage and the focus and palpability of images is a little scary at times.
I'm sure that some of this is due to the ZCD and some is due to the speakers.
If you ever decide that you could use a bit more in the "bottom end", my plate amp powered Hawthorne Augies are working out very well.
Happy listening,
Randy
