Did you read the Benchmark link? They believe that their switching power supplies are actually quieter than linear power supplies. The points they make about hum and magnetic interference are valid.
The Primare uppeer frequencies/timbre is unique among the class D amps I've heard. Their solution is proprietary, and works as good as a well designed Class AB (IMHO).
BTW, when I want to do serious listening, the Stax headphone setup (with SR 007) is what I use. I find it's superior to pretty much any regular playback setup. :-)

This may or may not be true, it could also be nothing more than an Infomercial from the CO and since I dont design amplifiers, i usually yield to others better than I, like John Curl and Nelson Pass to name a few and unless their position on this has changed recently , they think SMPS are a problem and prefer Linear supplies as I and I'm not new to switchers either , my first was for my bespoke Pre-amp in 78 , the pre-amp had a fantastic sound , but others could hear it switching , when close to it , i had isolated it to the AC line via a 14V linear supply the SMPS delivered 24 volts to the flat amp and phono stage when supplied with 14 volts ..It Bettered all my threshold pre's, a MC22 and was only bettered later by a ML26 pre in the late 80's ..
I still have it , so I'm not switching negative , just not sold on any superiority over Linear designs as of yet.
I have no issue purchasing a switcher, purchase will be based on performance , not because of ..

Until recently, always thought that switching power supplies were problematic. The Benchmark DAC 2 DX has better noise measurements than the vast majority of DAC's available. I think the point paper Benchmark put out on switching power supplies is valid, using state of the art devices and designs.
Agree with the statement that performance of the gear is the most important, regardless of design topology. Having said that, nothing I've heard so far sounds better than listening to music with the Stax headphone setup.
