I replaced a 2900 with the 3910 mainly because I wanted Denonlink and HDMI. Other than that, I was very happy with the 2900-it was a very nice machine and gave me hours of trouble-free playing time. If you don't need HDMI or Denonlink, it is a very good deck, especially for the HD audio formats. The only audio decoder it didn't have was HDCD, but there are even fewer of those disks than either of the HD formats (I have a couple thousand audio disks, and only a handful have HDCD encoding). I sold my 2900 for around $350 less than a year ago, and they are probably even cheaper now.
