I'm in the market for one of these receivers and was considering the 5860 because right now they are only $100 apart here in Canada. I thought the YPAO might be nice but I do have a sound level meter and used it on my other Yamaha receiver. I don't need really 7.1 (only have 5.1 for now) with no plans to upgrade to even 6.1. However, I was just at the another store and they have the 5850 for $349 and the 5860 for $528. At this price difference, I'm about to grab the 5850, unless I'm missing something. I can't get the comparison chart to come up at the Yamaha site but it appears the differences on the 5860 are basically: - 7.1 vs 6.1 - YPAO (parametric equalizer?) - Dialogue lift (is this really any use?) - Pure Direct listening mode - slightly more power - presence speakers Anybody got a good reason (worth $178 plus tax) to jump to the 5860? Thanks for any advice.
