I owned Ayre (V3) and Vienna (Beethovens) for about a year of great listening. I know these aren't the models you're asking about, but the newer Ayre is even better than the classic model, and the Mahlers like good solid power just like the Beethovens did. In addition, I think Ayre is a GREAT company that provides great customer service and product updates for very reasonable cost. Therefore, the V5 gets my vote.
