Probably not a reason for Pass Labs to discontinue the product, but soon or later a problem for building clones:

The PCM63 is out of production.

It was regarded as one of the best sounding DAC chips ever and although it features "only" a 20 bit resolution, it can still be found in some newer state-of-the-art DVD- and CD-players.

There are many ways out. I suggest having a look at David Broadhurst's DAC featuring PCM1704 or, if you like your circuit simple, some of the NOS designs with the old Philips TDA15xx DACs.

You can always use the Pass Labs I/V converter / output stage as long as your DAC has a current output.

D1

The last batch of parts for the D1 came from a broker, and took forever to get. That alone made the D1 more trouble than it was worth.

Nelson does not wish to make a product that we cannot support. So, we took the few remaining parts and put them on the shelf.
