I'd be curious to see and hear the differences between this latest Oppo and other comparable models. My Pioneer has four DACs of the same type as the Oppo. Will the additional DAC make that much difference, especially as the Pioneer has a dedicated stereo output and this Oppo doesn't? Would the additional picture quality make a difference on a 720p set or would the only be visible in 1080p? Looks like an audition is required.
