I'm shopping for a receiver and am confused about the mix of features offered by similarly priced units. ie not many seem to have pro logic II. the onkyo 595 seems well respected but doesn't even have component switching. the pioneer 810S does, but doesn't have pro logic II, same with the yamaha 5460 & 620. is pro logic II relatively new that it only went into a few of the manufacturers' 2001 models? is component switching a big deal? the kenwood VR-509 seems to have the features i want but few have it in stock. even the local CC said they're out and won't be getting them back in. is this model being phased out for 2002? when do the new models come out?
