Just get a ESI Juli@ sound card: Easy I2S from Juli@ PCI sound card

I've been trying to contact Pete Millett but have so far been unsuccessful. I've tried the email address on his website but so far no luck. Anyone knows of another way to contact him?

The Abrahamsen V1.0 CD Player runs an AK4396 DACs with an AK4125 doing upsampling, I would not be surprised if the same is true for this dac.

Good job.

If my memory serves me correct, the CD-A7 was one of Akai's top of the line players back in the late 80's. It uses the PCM53 DAC from Burr Brown, a highly regarded NOS DAC.
