Note that if it isn't sampling the DSD file at 284mhz you aren't really listening to DSD hardware, but just that the DSD support basically has a trick in the software to make the DSD file readable to the system but it's getting decoded by PCM hardware, not the 1-bit, 700X+ oversampling rates of DSD, and as such any improvements you hear is more attributable to an audiophile-specific high quality recording done when they made that disc than by using a DSD format.
I'm not sure if they work in exactly the same way, but in the mid to late 2000s Pioneer had entry-level universal (DVD) players equipped with a Burr Brown 24-bit DACs that have the SACD logo stamped on them. However, those 24bit DACs are PCM DACs, so what these players actually do was convert the file to PCM on the fly, then decode it using PCM DACs. I bought a $150 Sony SACD player and for the most part I can hear more detail than the Pioneer universal players, without sacrificing smoothness; however, by now I understand that there's the possibility that the Sony SACD player had a purer analog output circuit than the Pioneer (which may have been artifically adding warmth to the sound, which is all the rage with audiophiles).
