Though it may push a little higher... I really dug the Monitor Audio Silver series. 500 over the 300, but both rocked hard and handled anything I gave them.
And though I personally had issues, I will always give credit where its due, the KEF Q 750 or 950... listened to the 950. Impressive. My ears were sensitive to the Mids/highs, or some interaction with the room... but before the fatigue set in for me, I was impressed!
