Monsieurguzel,
I had the Atma-sphere S-30 for awhile, and I didn't like it direct from source. I was auditioning the W4S DAC-2 with the digital volume control at the time.The highs were a bit clunky, a bit harsh and unrefined. I tried it both balanced and single ended, didn't make a difference.
With the Red Wine Audio Isabella preamp in the mix things got a lot better.
As I understand, the W4S DAC-2 has a very good output stage, likely comparable to the Perfectwave DAC.
As in most things, no doubt your mileage will vary.
