MSB vs dCS Bartok

Thanks guys.
I have the “stock” MSB Premier 1x Discrete Power Supply - nothing extra.

I will play around with the settings George, I will even try the TOSLINK input as well. Just to make sure I have exhausted all options. I’ll even try and borrow a quality preamp. I have the Mola Mola Makua in mind.

Just get the Mola Mola  Makua with the DAC it's  Roon ready so you get it all in one box. 

rfc. is the unit returnable or exchangeable? 

I have asked that question today.
Awaiting the reply. Only issue is almost all high end audio manufacturing is shut down, UFN.

What stock dealers have now is it, for quit sometime I would imagine.

what other brands does the dealer carry?
