The video section of DVD players of similar quality can be rigorously compared. I like the approach of hometheater HiFi, where all DVD players are run through a series of tests designed to mimic the most challenging situations a DVD player might encounter. DVD Benchmark shootout.
If only we could do something similar with the audio section of universal players like the 2900 and 2910! Short of setting up a double-blind ABX comparison, it is basically impossible to objectively compare the sound of two different DACs.
Fortunately we have Nick, whose honesty we can trust because he has an unparalleled drive to spend as much time, effort, and money as necessary to get the best possible sound/visual experience BUT...not one cent more.
I look forward to learning from a reliable source whether the cheaper DACs in the 2910 result in a noticible difference in sound. Here's to Nick!
