Hi,

Long time Hifiberry customer. Love the products and you never fail to produce the next product I want.

My question is the following:

Can I build a system that uses the DSP functionality of the DAC DSP with the DAC+pro DAC.

Here is the additional information:

I currently have a Hifiberry Dac+ Pro fed directly to the 5v input on the DAC board from a linear power supply running runeaudio on a RPi3. 

I would like to keep the superior dual clock functionality with direct power feed of the DAC+Pro and add to it the DSP capability to perform room correction. How can I go about this? Do I need to add another RPI with DAC+DSP upstream of the DAC+pro? If so what output would I use to transmit from DAC+DSP to DAC+Pro?

Thanks for your great creations!

  Hi Shaun,

  you can't combine both. Also I would not recommend to do something like this at all. Ideally, in a digital there is only one master clock. If you're using the DSP, the master clock is the DSP clock. You con't need a dual-clock functionality as the clock of the DSP is always fixed. Converting it afterwards won't improve sound quality.

  Best regards,
  Daniel
