Makes some sense then, although with the new tweeks coming for Upsampler 2.0, I suspect even SACD will sound better. There are a lot of computer audiophiles who love HQPLayer for the same reason as the Upsampler, both make PCM sound better in most cases. Since most of my collection is ripped CDs, it was very apparent. It also makes a difference on even high res PCM. It also allows direct access to your music stored on a NAS over Ethernet, which has some noise advantages over USB. I have to say, with the Upsampler, I have tried almost every popular USB jitter remover, reclocking device sold and none of them improve the sound for the Upsampler - it is that good out of the box. Give it a listen in your own system.
