I have narrowed my receiver upgrade choices down to the Onkyo 898 and the Denon 4802. Since the Onkyo is significantly less expensive, I would prefer to go that route. However, after reading through the owners manual (downloaded from Onkyo's website), I have a few questions that hopefully existing 898 owners can answer. 1. Can the receiver be configured to use a single rear center speaker instead of two back surround speakers for 6.1 formats? My family room layout will not accomodate dual rear center speakers easily. 2. Can the speaker level settings be adjusted using a test disc such as Avia instead of using the internal test tone. The manual indicates that the test tone is generated automatically when entering the speaker level menu. A separate channel level function exists, but the manual states that settings made here are lost when the receiver is placed in standby mode. 3. The manual mentions that audible noises can be made when pausing a DVD while playing a DTS soundtrack. Is this really an issue in practice? 4. Does the "very dark" setting when using the DIM function for the receiver's front display work well? My existing Sony DA50ES has some bright red and blue lights that are annoying in a dark room. My current plan is to buy just a receiver for now and get used to the sound and workings of the component. Then, if necessary, I may add external amplification at a later date. FYI, my current speaker system consists of B&W's 600 S2 series -- 604S2 mains, LCRS2 center, 602S2 surrounds with an ASW1000 subwoofer.
