I see everyone has raved about how much improved the tray is on the 93. Personally I never had a single tray problem with my 83, but for some reason to me it feels like the 83's was a bit sturdier. I don't know why it seems that way to me, but it just does. Maybe something about how I think the 93's is a little longer, and comes out a bit farther, and this is giving the illusion of more flimsiness to it than the 83 had.
Like I said, I never had a single issue my 83's tray, and don't anticipate any probllems with this tray, so it's kind of a moot pont to me. Just thought it was interesting that everyone has pointed out how much better the tray is, and I prefer the older one.
Streaming on it over my media server however is just awesome! Very stable, haven't had a single lock up yet with streaming, very impressive. And can only improve through firmware upgrades
