I have had problems with SACDs skipping on my Denon DVD 2900. No problems with red book or dvd. I find that the Dark Side of the Moon SACD skips and stops playing the most of any of the SACDs that I have. The redbook layer works when I put it in my Rega Planet. This problem has caused me to reconsider getting my player modded. I am now looking for a better CD player.
