DSD recording

Hello,

Re: USB DAC Project for HPA

Thank you!

I´m following your recommendation: anyway, I need an additional I2C interface to µC to be able to configure filters and to read mode and sample frequencies.

USB DAC Project for HPA

Hello, I´m just designing a Class A Headphone Amplifier (Amplifier ready) and I need now an USB Audio DAC (PCM and DSD). The xCORE-AUDIO Hi-Res DAC/HPA Platform (with ESS DAC) is the ideal candidate but the Silicon XHRA-2HPA-TQ64 is obsolete. Can I replace this one with another one without a lot of ...
