Decided to go ahead and get the 5200 in hte end. All I can say is....WOW!! Outshines the Denon by far (in sound and build) and I am happy to report my sub has come back to life! I am once again a happy chappy. Only have two questions: What is the deal with the auto off thing? I turned it off yet at one point this afternoon the amp turned off. When turned back on it switched off again after a few mins. Had a fiddle with the auto off thing, turning it on and off several times an it seems to be fine now. Very odd but if its sorted, who cares! Also, when watching tv etc the volume is nice for normal viewing between around 35 - 25db, yet at the same volume for DVD's things seem a lot more quiet. Have to have it on around 15 - 18db to have the same volume of tv viewing. Is that the norm? Overall though I LOVE this amp, its just fantastic!!
