Opinions needed-fatigue


My system is as follows:Exposure 2010DS Integrated,Tavish Classic Phono, Pioneer PL-630 TT w/Shure V15ii cart,Audiovector M1 Signature on Target stands filled with Silica Sand,Transparent cables loom
Also, I guess part of the listening system would be my totl Widex hearing aids. Speakers are 6’ apart, 2’ from back wall. Listening chair places my ears about 6’ from them, and right at tweeter height, direct center. Imaging is great, separation is fantastic, for the most part very enjoyable. I have a thing for "audiophile vinyl pressings." Trouble is, I find the highs fatiguing past about the 9:00 mark on the volume dial, or right about 76 or so db (IIRC) depending on the track. Duane Allman solos, horns on jazz recordings, etc. Is it reasonable to think I should be able to listen louder at such close range, is there an obvious weak link in my rig causing the fatigue?

’speakers are toed in about 15 degrees.’ A major problem, I think. Most speakers are hot on axis and that is close to where you are. If you can, just for the fun of it, point your speakers straight ahead and see what happens - a potential problem though in a small room would be side wall reflections. If that isn’t possible, or the sound isn’t good, then try crossing the axis of your speakers well in front of your listening position (as previously suggested). Good luck with set up in your new room, small rooms are a bitch.
Just heard the same in big room with a little bit newer cartridge Shure V15III and more high end system. You can tame it a little - lower VTA (look tonearm height adjustment in manual) and try increase / decrease VTF to see what happens.
Many moons ago I owned the Shure V15 3 and 4. They would put me to sleep. Boooooooring!
