Since you didn’t change your room, I would say the speakers are the culprit. I agree more time may be needed. 100 or more hours is probably more like it.
Without calling for equipment change, here are a few suggestions. No particular order.
1) Isolation for both the CDP and Processor.
2) Couple the speakers with spikes.
3) Try a different PC on the CDP/DVD.
4) Try placing either a ring or 2 vertical bars of felt around/beside the tweeter. Staying about 1/2" from the driver itself and being about 1/2" wide. You can buy an easily removable two-way tape and attractive black felt from Michael's.
Isolation can help. Coupling can improve cohesiveness of the bass/midbass which effects the overall sound. I didn’t have good luck with that PC on my CDP. I really wanted to like it, but I kept going back to a Transparent Powerlink plus until I got a Virtual Dynamics P3, this ones a keeper. The Signalcable PC was to bright. The felt ring/bars can help reduced reflected energy and help absorb some of the laterally dispersed energy. You can also use 1/2"x1/2" or so adhesive backed foam. A soft one. Like you might use to seal around a window AC unit. I would still cover the adhesive with a two-way tape designed for easy removal or you might end up with crappy adhesive bonded to your new speakers.
