Update: After using this thing for about 7 months, it seems to be stuck in standby mode. I'm using a Mac, and the sound device shows up in Sound settings, but the unit itself shows nothing but a dot. Pressing the button just turns it off and on. Resetting the unit to factory settings did nothing. Good waste of a couple hundred bucks.
ptron3030whoa! Nice! Drop won't provide support as there wasn't a warranty and it's past 30 days. How'd you get in touch with Topping? tpdz.net? That website seems to be blocked by my company's firewall so I'll have to wait until I get home to check.
