Wish I could find a used M24 since it has PCM63 chips in it. I have had my share of PCM1704 DACs (I really like them a lot) but want to hear a good PCM63 implementation.
If you can hunt down a Theta DSPro Gen Va then by all means I suggest you go for it,
It utilizes 4 of the PCM63 chips. It will grab your utmost attention when you hear it.
It's like listening to vinyl, very analog sounding.
