I think it's safe to assume the VA-3 would sound as good if not better than the EM-55. Being a part of the VA family alone I think places it a few steps above too.. YOu get a way better looking keyboard with the VA-3 plus huge touch screen.. Starkeeper, how does the EM-20 sound compared to the 550? I do know the PSR-540 had 6 megs so I wonder if they were close to the same..
