David's board is complete DAC with I/V stage, output stage,and all regulators. It's really good DAC, I've built it so I can tell.
Jocko board is using the same chips but doesn't include everything. You need your own I/V stage, output stage and maybe more regulators. This board is perfect for installing in an existing player as an upgrade. E-mail Jocko for details.
Broadhurst board is good for building DAC from scratch, because it contains everything you need. However it's not silk-screened.
The problem with a 10 year development cycle in the "chip" industry is obsolecence.... the CS4329 chip is at least 8 years old. Given the increased support of SACD recently and a plethora of universal chips.... the decision is made easier.
Did all of you with Phillips pro transports get them from Homeoptics? Does anyone have a kit they have decided not to build?
Im considering a cdrom as well but I dont know if it will make a difference in sound from the Pro
