I suggest trying the following:
1. Ensure the cd player is not on the same circuit/lines as the amps and preamp. cd players and dacs generate much digital noise which is bi-directional meaning it goes back into the lines and infiltrates the other components. Only a handful of line conditioners provide bi-directional filtering.
2. I've owned the speaker cables you mention. Some to many cables and ics in this category induce much time smear which will contribute to the fatigue you mention. Try outfitting your system with the Speltz Anti-cables and Anti-ics. These are excellent cables and will cost you perhaps $300 total to outfit your entire system and you can return them within 30 days for a refund.
3. Try listening after removing your Panamax. Not all line conditioners are created equally nor are all worth owning. Some will even induce their own sonic harm. But you should still investigate in proper line conditioning.
4. You might also consider removing (at least temporarily) or heavily convering all reflective surfaces in the listening room. Including mirrors, glass, tables, etc..
These 4 areas are most likely the most probable contributors to ear fatigue you claim to experience.
-IMO
