although the AVR-525 is rumored to be on the streets already, i havent seen any detailed information regarding this unit online. the only H/K dealer in my area is Circuit City, and they dont have the new models yet. with the anticipation of the '525 being released, the '520 has recently seen a significant drop in price: Onecall is advertising its sale for $550 shipped! that being said, is the '525 worth the extra $200 plus waiting time? the only differences i can think of are two extra amp channels, DD-EX, and the lack of main-inputs. it also has a 2-line display, but that's not something to sell me on. have there been any other changes made to this model other than these? i dont have a 7.1 capable system (yet), and the $200 difference could be spent on an ICBM to universally manage my bass (i've always wanted one of these, and the 525 doesnt give me this option since it lacks main-inputs) or even on a used 2-ch amp. my question is this: what features on the '525 warrant the extra $200? opinions??
