Belts are generally the only problems with these, and as noted above, they are easily obtainable. The parts quality is very high, and on the CDP2 at least, the dual 20 bitBurr Brown D/A converters are a huge plus. I am always amazed that such an early CD player can read CD/R/RW discs...but these have no problem. Terry DeWick tells me that the MusicBank / CDPlayer design was the basis for some of the best McIntosh CD Players, and that the caps used on both the power supply and audio boards are top notch. Bottom line: IMHO the CDPlayer2 has beat several recent models (Cambridge Audio, Rotel, Marantz and [barely] NAD C542). These units are a pleasure to use. Great sound and beefy build are a sweet blend in a CDP you can find for pretty cheap! They were quite $$$expensive$$$ (upwards of a grand for the CDP2, 2RC) when new.
The (super high quality) motorized remote volume control is a seemingly silly feature that I have grown to love: the perfect compliment to any older system when you are crashed on the Main Listening Couch and realize that the your Silver Faced Receiver (supply a favorite here) needs to be be turned up or down a bit. I might be getting a little lazy....
