REGA Planet 2000 vs. Planet '3'


I realize there is no "Planet 3" CD player, but how can I tell if a Rega Planet 2000 has teh most recent upgrades to the lid and power supply (which warrants some to refer to the new ones as the "planet 3")? Is there a certain mfr date after which all player have the updates? Are there physically visible differences between teh two? Any info at all is appreciated. Thanks.

Yes , there is a large improvement over the Planet 2ooo by the later Planet 2000 {Planet 3 !!}.
Easy way to tell is by the loading lid.
Early ones had rounded edges and later ones square cut edges.
Hello,

If you could clarify where these edges are, I'd appreciate it. Specifically, are they towards the front of the player, the sides, the rear of the lid... ? Or maybe, do you happen to have any photographs or links to photographs about the differences? I'm concerned because I'd like to get the latest version of this player, and my local dealer doesn't seem to like opening merchandise boxes without reason. Thank you!
