After a lot of research, I've decided to upgrade from my Yamaha RX-V2095 to either the Pioneer Elite VSX-49TX or the 47TX. I know the 49TX offers the LCD touchpad remote, component video switching, advanced MCACC calibration and a couple of other upgrades, but is it really worth the extra $750 I would have to pay over the 47TX? I spoke with Scott at soundpros and he told me that if you sat down and A/B'd the 2 receivers with the same material you probably wouldn't be able to tell any difference sound-wise(which is the most important selling point for me). He did, however, try to convince me the 49 was worth the extra money for all of the features mentioned above. I don't mind spending the extra $750 for the 49TX if it is a much better unit, but I would rather use that money for other upgrades if the 47 sounds equally good. I don't really care about the remote or component video switching to be perfectly honest. I'm just wondering if anyone in here had the same dilemma choosing between the 49TX and 47TX. If so, which did you go with and why? I'm going to make my purchase on Monday and if anyone could respond before then and help my decision process it would be greatly appreciated. Thanks in advance for your help. Oh, by the way, to owners of either of these units--do you use one subwoofer or two in your system? I'm currently running one with the Yamaha, but I've thought about upgrading to dual subs. Is it worth it or will one suffice?
