I have done some trials with SoX upsampling to 352.8khz and comparing DXD (PCM) and DSD256 (Native) output with Foobar2000+AsioProxy. I definitely like the DSD output more. And i like both more than just plain 44.1khz output, which really does not sound bad either. I used to be against upsampling, but i think DSD with a good upsampler is a game changer.
This is with MSB The Analog Dac with Premium Quad USB 2 module. I think if the FDAC will have a good DSD512 support it has a lot of potential. Upsamling+DSD256 takes about 5% of my

I think more people should experience the DSD x2/x4/x8 (and with proper upsampling, SoX and the like, not windows upsampler). There seems to be a fundamental difference to the better even tho the original material is "just" CD-quality.
