Why are you asking? Are the reviews not credible enough? Are you too nervous to pull the trigger on a relatively inexpensive highly reviewed and credible product? Not sure what the handwringing and complaining from the others commenting here is about. The units get great reviews and are not prone to any problems so not sure of why the focus on "terrible support" is. I have two DMPa6 I use as pre amp DAC/Streamers into power amps. They're dead reliable, highly flexible and sonically neutral. Not sure how they'd ever need support either- and - unless you're talking Audio Research and the like customer service and support are a nightmare everywhere with companies just not responding ever. I'd pull the trigger and buy one and enjoy it, there are enough great reviews out there that ensure its a solid performer with a great interface.
