Happy Holidays to all! I have read product brochures, spec sheets, ad literature and all the posts in this forum, and I'm starting to go crazy! Every time I think I understand even 60% of the factors that I should use as buying criteria for my new HT receiver some article or post or spec sheet uses the numbers/stats in a slightly different way - making me less sure of the qualities I think I need/want in this next box. I think I have the choice narrowed down to the Denon AVR 3803 and the Marantz SR8300. Kudos to Bob McElfresh for his chart on receivers, but it doesn't exactly state these two receivers specs as they are laid out in the product spec sheets from each companies web-sites. I have listened to both boxes outputting to the same speakers and can't really hear enough of a difference to make the decision based on ear alone. I guess I am now more focused on features, build quality, and upgradability/slow obsolescence. Specific questions I have are: Power/Channels : The SR8200 is 120W x 6 and the 3803 is 110 x 7 - what does that extra channel really buy me? Isn't the decoding that sends sound to the 'extra' channels above 5.1 matrixed anyway? Is this really only useful for better 2nd room amplification? If so, will the 10W difference make a difference? If not, what am I missing here? Others may need to understand the finer points of this comparison also. Component Quality Etc.: The SR8200 is a certified 'THX Select' box and the 3803 isn't. The 3803 literature makes a big deal about their 'Melody 100' DSP, the 24 bit 192 kHz high res Burr-Brown DAC for all channels, their ability to auto store surround modes for 4 input sources, and their ability to use 'Component Video Conversion'(although some on this forum haven't been too impressed I've noticed). The SR8200 touts their 'Crystal' 24/192 DACs, their massive toroidal power xformer w/ oversized filters and high output wattages/current, their adaptive dual differential mode for 2 channel independance, and that all of the digital, analog, and control circuits are have their own power supplies and are separated and heavily shielded to prevent crosstalk and interference. So . . . does either's impressive component architecture make a big difference in quality today and tomorrow? Will either be less able to handle future sound needs? Specifications/Future Upgradability: With exception of their channels/wattage, and THX certification, both of these receivers have almost identical THD, FR, and S to N ratios. The Denon has one more composite and S-Video input and apparently 3 more Audio inputs than the Marantz, and some other features as well. The Marantz has an RS-232C connection for upgradability that isn't mentioned in the Denon literature. The Marantz has two assignable DC triggers and the Denon has one (what are these used for??). The Denon has an adjustable xover for the sub, and I can't tell from the Marantz if it is adj or fixed. With the price of these two high class receivers being so close . . . . which one really will give me more bang for my buck over the long run (next 5-10 years or so) and why?? Thanks for helping me get out of my hopeless Analysis Paralysis!!!!
