Causes of long term listening fatigue?


I like to listen to music continuously for hours mostly at low volume levels. For me therefore, it is important to have a setup that will not cause any listening fatigue (lf).

Now I am looking for a new speaker setup and I wonder whether people could comment on the following aspects:
1. is 5-ch more susceptible to lf than 2-ch?
2. are there quick tests so that one can determine whether a given speaker will tend to give lf? I ask this because in a shop it will be difficult to assess this due to lack of time and differences in acoustic environment.
3. Which speakers do you know in the price class $3k that do have lf problems and which ones can be recommended in this respect? (difficult question, I know).

Thanks for input.

The biggest cause of listener fatigue is worrying too damned much about your gear.
Experience has taught me that the problem is usually in the electronics, and NOT the speakers.
When I had some big Infinity speakers, and a Hafler DH110 from a kit, with a Carver amp. I was in heaven.
For some mysterious reason, I bought a gizmo laden Sony ES digital preamp.
My musical listening dropped off to zero.
After awhile I figured out that it was the Sony.
I bought a Counterpoint pre. Heaven again, (when it was working...)
Finally I bought an Adcom. Not heaven, but good enough to listen too... and it is reliable.
I have a SCD777ES for digital, and a Audio Research PH-2 for vinyle playback.
Speakers... who cares. As long as they are reasonable, they do not create the fatigue problem... they only "pass it along" from the electronics.
Power conditioners also help ease the problem a bit. But what you need is the right electronics.
So the speakers, IMO, are NOT the problem.
Want to add that my statement was only in regard to "listener fatigue" and not the many other problems that can be associated with speakers.
Thanks
IF there is the slightest degree of "brightness", I know something isn't going to work for me.
Consider Vandersteens or similarly smooth speaker if in fact your speaker is lean or bright. If any component sounds very exciting upon first listen, it might be a problem over time. I also agree about electronics and will add cable problems as well. Watch out for ultra detailed sounding anything...it might lead to fatigue over time.
