I searched the forums for amps recommended as a good match for my speakers and that worked out well. I bought used - I assume for $3K you are too with those brands - so no problem if I didn't like the amp. I would resell and try again, if it came to that.
My speakers have level adjust on the tweeters and mids. Oddly enough, I find a hot tweeter level is the source of the intolerable "midrange glare" while the midrange level has little effect.
