I'm looking to upgrade my receiver (avr520). I've looked into the Rotel rsx1056 and the HK avr7300. Both of these seem great on paper and each has their strong points. I'm looking for a good 5.1 receiver with extensive bass management. Are there other brands I should consider? I do have denon dvd2200 so SACD inputs are a must. 6 or 7.1 is not neccessary because of my room size. I am driving Axiom m60's for fronts so I do need at least 65watts.
