My system's high frequencies hurt my ears

Well, to be perfectly clear it doesn't always hurt my ears but I've been getting a little fatigued at times and I'm trying to diagnose the problem. A few nights ago I was listening to a new 24/96 The Doors first album release and had to stop playback. I switched over to The Eagles Greatest Hits, 16/44, and found some happiness there but I wasn't completely satisfied. Perhaps some of this is psychological, maybe I was feeling a little extra sensitive, but I'm sure I've had some issues with high frequencies in the past.

Here's my setup:

Serving all music, ripped to WAV by Exact Audio Copy or downloaded via high rez sites, via Windows 7 computer running J River set to WASAPI output. Sending signal via USB to Audiophilleo USB/SPDIF converter to PS Audio Digital Link III DAC. From DAC using Nordost Baldur unbalanced RCA interconnects to PS Audio C-100 Control Amp. Speaker wires are Nordost Blue Heaven. Power cables are PS Audio Lab Cable from wall to PS Audio Duet Power Conditioner. From there I use another Lab Cable for the amp and a PS Jewel cable for the DAC. The wall plug is on its own circuit with nothing else connected. Speakers are my old but good Mirage 1090i's.

Aside from perhaps the age of the speakers do you guys see anything that stands out? I spoke to a technician from Mirage and he suggested I'm doing too much signal processing which could be a cause of uncomfortable high frequencies.

Looking forward to hearing your thoughts.

I'm having a bit of trouble with this. I have an isosceles triangle with two angles being 64.6 degrees and the angle of my listening chair being 50.8 degrees. The triangle sides are 120 by 120 by 103 inches. When I draw the perpendicular line from the right speaker I get another isosceles triangle. I'm missing a line somewhere.

OK my assumption that your listening position was further from the speakers than the speakers are from each other makes my suggestion a bit obtuse. Lets see if this will work, rotate your speaker(s) until the axis is approximately 18 to 20 degrees past your head position. Listen for a while to the new sound (I would do it for some days - just getting used to hearing it). Then then start rotating the speakers back towards your head until the sound improves or deteriorates. When it deteriorates stop and go back the other way by say 50%. And so forth. You should find a sweet spot some where in the range.

Also, since the rear of your speaker is now likely pointed at the side wall/corner behind the speaker, you could temporarily hang a heavy blanket on the wall to see if deadening some the speaker's back tweeter will be beneficial to you. Or if that is not possible, you might try hanging a blanket or two on the wall behind the speakers helps at all. This is all trial and error stuff but if you find a real improvement you can always find domestic materials from bookcases with books, drapes, plants etc which will serve nearly as well as high end and ugly acoustic materials.

This is a slow process but can really be worthwhile.

That's great news, Robpriore. Dramatic evidence for the importance of placement.

Likely speaker and/or room. I'd replace those cables with regular Blue Jeans cable too.

Quit worrying about degrees and types of angles!!!! Find a position that you like and leave them there. You'll drive yourself crazy playing the numbers game. Just my opinion.
