I would take Onhwy61's advice seriously. Other than an overwhelming mid-upper register (say, ~2-6kHz) that is tiring, the physical malaise you experience shouldn't be there. UNLESS of course, you listen really loud (and 10-12 on the volume can be pretty loud). Keep to average levels of ~78-80db spl max.
Do you have any light switch dimmers or flourescent lighting in or around your listening room? No one is going to hear 30k or 40khz but it will give you a headache and ringing ears in a short time. At the very least try and get a SPL meter and see if you have any ultra high freqs bombarding you. Also try and put some cheap out of the box IC's and zip cord just as an experiment, but use it everywhere. Try the free and cheap first. Good luck.
Vertigo, that would be waaaay too much toe-in for me. Try aiming your speakers at a point behind the listening position that is equal to the distance from the listening position to the speakers (7 feet behind the listener, in your case). If there is enough room between the side walls and your speakers that first reflection aren't a problem, I would try aiming them at a distance twice that far behind the listening position. I realize toe-in is really subjective and depends on room, speaker, gear, etc., but that amount of toe-in would drive me insane...not to mention that pointing the speakers directly at the listener's ear destroys soundstaging in a very substantial way. Try changing the toe-in combined with using something handy like towels or rugs for taming first reflection points and see how it sounds. At least it's easy and cheap! Hope that helps.
hey guys,

xxx I think you need to seek medical attention. Listening fatigue is usaully a mental state xxx

Yes the sympton is physical. It is tinnitus or tinnititus , however its spelt. It is not boredom or irritation or something emotional as a result of listening to music.

....But if the higher frequencies are bright doesnt that "fry" your ears with prolonged listening? Isnt it a sliding scale. "Perfect treble" is sweet and enjoyable and probably more tolerable at certain volume than a less perfect treble at the same decibal level.... but nevertheless even perfect treble if played at very loud levels will make your ears ring.

No, no light switch dimmers.

xxxx you are damaging your ears and it is irreversable... xxxxx

yes i know. I did have a hearing test about 3 weeks ago cause i was worried and she said my hearing tested normal.

About toe in and set up i used the forum advice and set up example in the following thread

The xa777es is really good, probably more neutral than it is romantic and maybe the golden cross ic will warm things up and help a bit. How many hours can you guys listen for without any bad effects? 2, 4, 6?
