Likely less expensive to replace the laser assembly on the CD2 than buying a new player.
Also the following is copied from the Audio Note CD2.1x owner's manual:
The CD2.1x uses an 18 bit chip that truncates the information to 20, 22 and 24 bits. The info you post regarding 20 bit and 24 bit as it relates to the CD2 appears to diverge from that published in the CD2.1x manual.
Perhaps a 20 bit player is not what you seek after all...
FWIW, the Paradisea DAC utilizes a TDA1545A chip that is 16 bit.
Also the following is copied from the Audio Note CD2.1x owner's manual:
18 Bit 44.1/48/96KHz compatible multi Bit converter chip, the 1xoversampling system will truncate the information at 20, 22 and 24Bits, which is very much milder form of information loss than that introduced by traditional over sampling and digital filtering etc.
