Original Rega Planet Question


These seem to be appearing frequently on Audiogon...is the newer version that much better?

As an owner of the original then upgraded to the new (my present player), thought the original is good, I can say that the Planet 2000 is better. I did a good hour comparing the two switching back and forth in the same system and the (forgive my weak grasp of jargon) bass detail, space and openness were noticeably better. A more life-like and cleaner sound; more air around the instruments and more texture to the voices.
The original planet was a big seller so there are tons of them available. I recently upgraded to a Linn Ikemi and while the Linn is an improvement, we are comparing a $3600 player to a $750 player at list. I decided to keep my planet for use in a second system rather than sell it. I've not heard the new planet, so you'll have to let your ears be the judge (as you should anyway, this is a very subjective hobby).
Does anybody have knowledge of Rega Planets or Jupiters being modded? Do they make good transports? Thanks
