I have not yet compared either of these models (hoping to get to see the Yamaha S1500 in the next week or two, ideally alongside the Denon 2200). The Sony isn't actually a universal player, though -- it will do SACD, but not DVD-Audio. Both the Denon 2200 and the Sony 555 have been included in the Secrets Shoot-Out , and in that the Denon had a better showing. All of the tests that the Denon failed or was borderline on were shared with the Sony, but the Sony failed or was borderline on several other tests as well (including a four-second layer change). In the end, the Denon scored an 83 overall to the Sony's 69.
