Hi and i admit to be quite out of my field
But reading elsewhere i have seen that when the aim is to set up an "audiophile" pc, the off-the-shelf solution is hardly the best choice.
A MAC mini is an all purpose PC ... it must do a lot of things not only playback audio.
It is a long selection process to find the best MB, power supply, CPU, OS and so on.
I would follow that route instead of picking up a commercial unit and try to put a patch here and there.
Not all the MBs are made equal so the PSs and CPUs
For instance many off-the-shelf units come with video cards embedded
Is it needed for audio ? no. Could it give issues ? maybe.
No fan should be present in an audio pc this i have concluded recently. A passive cooling is mandatory.
Absolutely no spinning hard drive
We should limit the causes of those spikes at the beginning as long as it is possible.
For instance i like very much the PCI caps bank solution, impossible to use in this case.
To end i guess it is quite difficult to find a very good off the shelf unit for this specific purpose.
One day i will set up a specific pc for audio from components (these off the shelf of course).Just one last though ... i am still convinced that if an usb dac is very well designed and built it makes all these discussions of secondary importance and one can select the pc on the basis of its look for instance and the Mac Mini is quite fantastic on this aspect.
Nice object.
Thanks again.
Kind regards,
bg

You should try to understand and accept that we are dealing with a 'system' and that the components are interdependent. To think otherwise is simply technically foolhardy and comes from what I call 'conviction' audio whereby one simply defines the dac as the unique culprit. This is convenient for vendors, as some can conveniently dismiss the influenec of components other than the ones they make and sell.
....'conviction' audio whereby one simply defines the dac as the unique culprit.
Can easily be said of those who define the PC as the unique culprit, don't you think?
And since you mentioned 'the system' wouldn't it also be reasonable that certain components in 'the system' might have a greater overall effect on the 'system sound' than another component?
Did you not see my question to you linked below?
