Dirac without losing resolution

Thanks for all of the feedback.  I agree that most of the source material is within the limits of these dirac devices.

For those of you that are using it, how do you have it connected?  Ex between the streamer and dac?  If so, which connectors are you using for the input and output?

I was hoping to at least connect my PC via its USB to the minidsp but not sure if it even has a USB input.

Does dirac need to work in the digital domain?  If not, can I connect the analog output of the dac to the input of the minidsp?

Dirac needs to work in the digital domain . . . that’s why it’s called DSP (digital signal processing). That kind of processing is not feasible in the analog domain. Until recently, processing typically was done at 48 kHz or 96 kHz, so 192 kHz is current state of the art.

Some DSP devices can be fed with an analog signal; however, it is converted to digital before processing and then re-converted back. So I would not advise doing DAC before Dirac, as you’d be adding a DAC-ADC cycle to the signal processing. In my experience, the fewer conversions, the better.

Thanks again for the confirmation.

That still leaves the question as to which connections for the input and output to at least get the optimal resolution.

The answer already given is digital and the particular nature would depend on what is available on the specific miniDSP and the HiFi Rose devices chosen.

Let me try and be more specific as I now understand that it needs to be digital.  My PC currently only has USB.  I couldn't clearly confirm if the minidsp devices have USB in and USB out.  That is why I was asking those that are using these devices.
