Power supply design sign is very important especially if you want to avoid power conditioners, fuses, after market power cords and all kinds band aids. (Another discussion for another time might be why high end boutique manufacturers so often get power supply design aspects so badly wrong - creating a "band-aid" market)
The Benchmark DAC3 and their ABH2 amp achieve performance standards that exceed everything else and one of the reasons is a Switched Mode Power Supply. In fact there is an interesting article devoted to debunking the myth that Switched Mode Power Supplies are noisy. I am not sure I entirely agree, as I have found SMPS to be troublesome in the past, however John Siau explains why SMPS done correctly can lead to tremendous reduction in the noise floor.

In light of these advances I find myself forced to accept that linear Power Supplies may be easier to build correctly but SMPS done right can be SOTA and better than everything else.

30db additional reduction in noise floor over a linear power supply is a major paradigm shift in audio design!
