I have to say that Readster's high end CDP choices are stellar. At the same time, I've heard a number of players that outperform the Jolida under the 5K mark, and selecting one is simply a matter of sonic preference. The Audio Aero Prima is a phenomenal player, and in my experience it is superior to the Jolida in every regard, despite the benefits achieved with a tube upgrade. Others of note (search the archives here, as well): Resolution Audio Opus 21, Muse, Cary, Audio Note, Consonance, etc.
While some players do tend to sound more digital, there are others that certainly offer better resolution and dymamics than the Jolida, and yet still have a warm analog-like sound. Many of these happen to be, not coincidentally, tube players.
