I have the older Rotel RSP-1570 and NAD T175. For Rotel firmware updates, I can download directly from Rotel website. For NAD pre/processor firmware updates, I need to get it from their dealers since it is not available from their website.
Why this is important? When I bought RSP-1570, it does not come with 3D pass through, but that feature was added later with firmware updates. My T175 is already obsolete.
