I'm intrigued by this whole upsampling thing, since I will do about 60% Music (redbook cds)/40% Home Theater. Just a few questions: First of all, will the upsampling only work on an analog output into my 45tx? Will the upsampling improve quality on cd-rs (burned cds)? What exactly do the firmware upgrades 'correct'? (lip sync issues, angle icon, etc.), and are all the new ones shipping with this update. I had my heart set on an ELITE 45A, but now I think this will be the better choice. Thanks for your time.
