"Yes. Things sound a bit less digital with the upsampler, a bit more extension, soundstage, etc...but the difference is not that great. I do not pretend to be an ee so I can't say how my dac really gains by the upsampling. While there was a noticable improvement, it was subtle."What I have observed is that when listening to an upsampling player (I have 2 under my belt right now) is that the noise is really low, and the term "notes arising from an inky black silence" is, while overly dramatic sounding, appropriate. DIdn't notice any noise or grunge, and the music, to me, was very engaging.
From my background (I *am* an EE), upsampling through its interpolation from 16/44.1kHz -> 24/192kHz or 96kHz will reduce the quantization noise (called "noise shaping") to low levels and out of band at the same time. You will probably have the white noise being higher than the noise due to the artifacts of the digital encoding and decoding - which will make the noise floor that much more pleasant since it would be free of atonal artifacts. It will also be able to retrieve more bits into music (the problem with DAC's is being able to decode all 16 bits - this is a way to be able to get more of the information D to A'd).
