It's not a wide range of samples, but I have 3 recent shows recorded V3>AES>722 and now two shows V3>line>722 all at 24/96.
I have not burned any DVDs so I have not listened to them on the big system in a way that allows a decent comparison. General comments are that there is a distinct difference between V3 ADC and 722 ADC but I do not have a preference at this point. Also, the use of the V3 as pre-amp really seemed to improve the sound over the 722 preamp alone.
