I have to say that I am enjoying the sound from my DIY Purifi amps a lot more than the Nord NC500 amps I had last year. I don't know if this is because of my use of a large linear power supply in my DIY amps, the difference between the Purifi module and the Hypex module. the difference in input buffers, or other changes in my system. But these new amps are much more dynamic and engaging.
I don't have the experience or knowledge that atmosphere or audio2design have, but based on my 45+ years experience as an audio enthusiast and tinkerer, a good power supply makes a huge difference in the sound quality of all audio electronics. I don't doubt that it's possible to achieve this with an SMPS. But either way, I think many (most?) class D amplifier companies are not making the effort and/or are not willing to increase their parts cost enough to deliver close to the full potential of what class D can offer.
