Hi,
Rega Planet 2000 and Jupiter are good players .. as everyone else stated it may be because of the tubes Jolida is more musical .. I bought JD-100 Mod 1, after comparing it with Rega (both), NAD silver series, Arcam FMJ 23. I am happy with Jolida JD 100, but in my case it was good upgrade from Modified Samsung DVD player, I am not sure that is the case with you if you want to move up from Rega Planet 2000, given the choice I will wait till I can afford Audio Aero Prima.
Regards,
Milind
