chichazI posted a photo of the remote. Three of the buttons (PLL, Bri, and INV) have no function, but it is a useful remote. You can read my review. I'm very pleased with the unit.
chichazI bought the "advanced" model from Drop for $612 + $50 tax. I have DSD music files on my Windows PC, but I think it converts them to PCM for USB output. The Singxer user guide says it can play DSD, but I can't confirm that based on my use. My OPPO Blu-ray player plays SACDs, but does not output DSD via coax or optical outs.

DSD cannot be output via these formats, as they're limited to 24 bit / 192kHz resolution. The analog outputs should put out DSD, however, if it's set to in the menus (I have an OPPO too, though I use it mostly for for SACD ripping).
If you're using foobar2000, there's a way to 'trick' the DAC into receiving pure DSD audio or DSD via DoP, both from the USB connector.
I saw the reviews on Head-fi mentioned below so I'm all set, but thanks for replying.
