RegaPlanet Original vs RegaPlanet 2000 vs Jupiter?

I owned the Planet 2000 and I've nothing to say but positive. You can get a used for around $600-650 and I think it's definitely one of the best, if not the best, in the market.
It's a substantial upgrade to the original. I won't bother with it unless you can get it dirt cheap or unless you've a certain budget.

Hope this helps.

I have both the Planet 2000 and the Jupiter 2000. I would recommend the Jupiter 2000, although both are excellent. I use the Planet in my office in a lesser system and the Jupiter in my main system with a much nice amp (the nicer amp helps bring out the nuances of the Jupiter). The Jupiter is simply sweet! Worth twice the price? Who knows... but the whole is bigger than the sum of the parts to my ears. I think the 2000 series components would be a better choice because the older units are already that much older. But let your ears decide. You could also compare the reviews of the new vs old on Audioreview.com to get a sense of their character. The older Planet seems to be thought of as more laid back than the 2000.

If you buy an original Planet, my experience with an inexpensive mod my interest you. I owned an original Planet and obtained a very nice improvement by replacing the powercord with a 15 amp IEC to allow aftermarket powercords...a lot of improvement for a little money!

I was wondering all those three cd player play CDR?
