Thank you for your enquiry. We will get back to you as soon as possible.
From our years of experience building power supplies, we have realized that there is no one universal power supply design that is the best for all application digital and audio. Within the broad architecture design (macro view) there are further optimization in the micro level (component selection, grounding point etc) that can improve the performance further. It is with this experience and knowledge that we create our PLiXiR PC linear power supply.
We recommend the flagship Elite BDC Balanced DC power supply (19Vdc 4Amps version) for the Roon Nucleus and Nucleus + for the best performance. For NUC (19Vdc 6Amps) and Mac Mini (12Vdc 6amps), we recommend the cost effective Elementa DC power supply.
We can also modify your Mac Mini to remove its original internal switch mode power supply to accept an external linear power supply (2.5mm DC jack). We also mod the Mac Mini internally in this case with additional filter capacitance that is soldered in. The modification will cost SGD$150.
Highly optimized power supplies for Mac Mini, Roon Nucleus, and Intel NUC with specified components and construction methods.
