@jafant and @tomthiel: So this morning I went to home depot and bought a little lazer measuring device and realized I got the eyeballed measurements all wrong. The distance between the speakers is 8’11". The distance from each speaker to my seating position is 12’9". The speakers were previously -- when you heard them jafant -- about 7’ apart. The new speaker cables allow the approx 9’ distance. So the CORRECT MEASUREMENTS explain alot. The room is irregularly shaped (which may also explain alot): thus, the distance from the right speaker to the side wall is only 2’ and the distance of the left speaker to the side wall is 4’5". The distance to the rear wall in both cases is 4'10". Previously in the narrower spacing I had the speakers facing forward; in the current wider spacing I have them toed in. As I’ve said even toed in I don’t experience them as "bright" although I know some folks do and elect to eliminate toe-in. I’ve attached another photo which shows you a little more about the irregularly shaped room, the disparate distances between each speaker and the side walls. Note that farther into the room, the room narrows a bit to the area of the seating position. As I explained in my earlier post I’m somewhat stuck with seating position although I have a little window within which to adjust the speaker positions. The Powerpoints have been in use as the right and left channels of a video projection system with a screen that comes down from the ceiling (you’ll also if you look carefully see an SCS3 center channel there near the ground level ). Here’s the additional photo. https://www.dropbox.com/s/qm41tvx4on9amvr/IMG_7273.JPG?dl=0

@gasman117 our hearing usually gets attenuated (reduced) as we age and its the high frequencies that go first so that's unlikely to be the problem. Still, we all recordings and music differently and have different preferences...one man's clear and incisive is another man's borderline "bright"/bridge too far.
For those who are interested, I’ve attached another couple of photos of the room trying to capture this strangely shaped space on the fourth floor of a 4100 sq ft townhome. ALSO, in addition to the Thiel 2.4’s which I utilize for more serious two channel listening, I also use the room for movies and the room incorporates a pair of powerpoints right and left front, an SCS3 center channel, two additional power points on the ceiling at the rear for rear surrounds, and a pair of powerplanes installed in wall as mid-surrounds. A JVC DILA RS520 is employed as the projector. The middle of the long gray sofa is the seating position for serious 2 channel music listening.
OK, a little removed from the "speaker" thread, but at least related: I run my 3.7 speakers with a Classe CA-300 amp. It has developed a slight hum audible from the tweeters. I've found someone in my area who works on this kind of thing. I'm wondering what other upgrades to the amp I might ask for besides just fixing the hum. Any amp hotrodders out there who can offer suggestions?
