For years, I ran EPOS 11's with an Adcom 545 power amp and Adcom 500 II tuner/preamp and they sounded great ... not harsh or aggressive sounding by any means. The EPOS house sound is not a bright sound, at least not to my ears anyway. By comparison, I find the B&W series price equivalents (300 & 600 series) to be bright sounding (treble emphasized). You may wish to experiment with the EPOS placement, as I found them very different sounding depending on placement.
