I have both these DVD-As. The first question is if you like the Chicago sound and music you already know? If your answer is 'yes' then I would say you that you should be very happy with both these discs added to your collection. Both of these discs will give you crisp surround separation of many layers that are the Chicago sound. As with most DVD-A, the availability is getting scarce and driving prices up.
There are many good and many bad titles out there. What are you looking for in music and is discreet multi-channel part of your criteria? We share the Oppo 980H so the world of SACD is also available to you.
