Thanks for the tip!
I have considered that, and tried direct source from the CD, or from a denon micro player i have too - all have fatique. Using the Bushmaster as a Dac reduces it (in this case i also use ALAC files from Ipod as a source)
It is possible that all of these are creating fatigue - as well as the speakers... in any case the new speakers and amp have not arrived yet, so when they do - we will know more!!
If an opportunity comes up i would gladly add a new cd to the pile, and try it out too
