Or, if anyone is in the SF Bay area and would like to listen to or borrow the DAC, just let me know. Maybe next meetup we can do a proper comparison test. And, there lies the problem with Burr Brown. Onkyo has replaced the old trustworthy Texas Instruments Burr-Brown DACs for the new AK4458 DAC from Asahi Kasei Microdevices Corporation. Unfortunately I ended up getting so carried away listening to the new Cavalli Audio amps and Questyle amp that I didn't have time to demo the CS4398 for anyone there. Burr Brown, Cirrus Logic, Analog Devices, AKM, Wolfson all supply a wide range of DACs. I brought the DAC to the most recent NorCal HeadFi meetup. The CS4398 DAC AFAIK is mainly used in high-end home theater and hifi, such as the Marantz CD6003. I have mainly used it between my mid-grade Sony CD changer and my Beta 22 headphone amplifier. This board happens to be available at Digikey for ~$450, but you'll also have to buy a power supply for it. They're cool because you can fiddle with the DAC settings like different sampling modes. Usually anyone can purchase evaluation boards for any chip. I picked up one of their engineering boards for their flagship DAC, the CS4398.
I used to work at an audio chip maker called Cirrus Logic. This post is just to tell folks a little about the CS4398 DAC.
