![]() ![]() 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. 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. ![]() 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. have no idea what that meant but thanks man Tone, 7 timind likes this. ![]() Now I am beginning to think that this is not possible. The DAC is a Cirrus Logic CS4398 and is not in your supported DAC list (needless to say I did not know this when I set out on this plan I naively thought any DAC would do). This board happens to be available at Digikey for ~$450, but you'll also have to buy a power supply for it. If you want to see chips, you can multiply 1 a chip x a billion devices in revenue for things like iPhone and Samsung bridge chips, lightning-3.5mm adapters, airpods, etc. I planned to use the built in DAC in my Marantz Tuner (NA7004) which can be connected to the RPi via USB B. 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. 32-bit resolution stereo audio DACs that support up to 384kHz sampling frequency. This post is just to tell folks a little about the CS4398 DAC.
