This has been consistent with my system with every software update for the last year. I think Meridian has it setup this way to easily integrate their older DSP speakers that can only play up to 48kHz.

When I first saw the way the "Force 1x" worked (everything at 44/48 or 88/96) I sent an email to Meridian asking for a "Play Native Resolution" option that would just play the files as they are without upsampling or downsampling, I guess that's not going to happen. It doesn't seem to hurt the sound quality having the Sooloos upsample CD quality files so I guess it's not a big deal.

So much music, so little time.
