Equalizer or acoustic room treatment or?

I have a high end stereo system: sony sacd-1, musical fidelity ss amp promitheus audio tvc, snell reference A-5 towers ($20,000) ( towers with external crossovers and huge stereo subs (approx 4'x2'x2') driven by parasound ss amps. The room is 24' by 12' with speakers at the far end. Room is carpeted and has furniture.
Here is the issue. The sound is extremely accurate and revealing. Its so accurate I find it fatiguing to listen to. I think this is due to starting w/ cd's which I always thought had too much of an "edge" to the sound combined w/ very accurate components.
I would like to smooth out or soften up the sound. So far everything I have played around with takes away from the accuracy and detail (slightly) without softening/smoothing enough.
Suggestions? EQ? Room treatments?
I have tried different dacs, tube buffers and they did not cut it.
Look at it this way: I think I hear the sound exactly as it enters the mics. I think i would prefer the sound as you get it as a listener sitting at a live performance.
