I have not tried JRiver in a long time. I heard the current version is significantly better than previous versions I tried about 2 years ago by quite a bit.
Over the past 2 years, I have been using XXHighend. All I can say is that when I started using XXHighend, it was significantly better than foobar, mediamonkey, Jriver at that time. Since then, it only got better and better. I don't know if Jriver has caught up with it or not. The only weak part of XXHighend is the interface is not nearly as nice as mediamonkey or Jriver and I feel that to get the most of it, low power PC/laptop is not going to work. You really need lots of RAM and seems to sound best at this time with Win7 with service pack 1 (not official release yet but you can get them).
