Well people I have burned in My power 2's (about 300 hrs on them) They are wonderful! My Rowland Model 3's are finally singing. Great soundstage, goes about 2ft. beyond my speakers on the right and left. It is a little deeper on these compared to the power 3's. Detail is great, bass is strong. which I need because I am still using a pair of Epos ES-11 speakers.
