Musiland Audio Labs Monitor 02 US Dragon USB2.0 / USB3.0 Desktop DAC/Headphone Amplifier 32bit/384KHz. We installed the newest driver from the included CD onto a Windows 10 x64 system and it worked flawlessly. In conjunction with our media center, as you can see from the photos, we were able to effortlessly switch between bitrates. (Though not shown in the photos, we were also able to effortlessly switch between ASIO and WAVE.) This thing is rock solid and sounds fantastic. Definitely audiophile grade. The imaging is insane. Everything we threw at it sounded great. And the headphone amplifier, which was quite impressive, is very powerful indeed. Its in great condition and everything works as expected. The manual says it is normal for this to get warm during extended use, but we experienced nothing of the sort. It stayed cool as a cucumber for hours, as did the power supply, running primarily at 96K. The manual is on the CD but it is in Chinese. Thank god you dont really need it. (You push down gently on the big volume wheel to mute/unmute...that is what we learned from the manual.) There is a Chinese-to-English text of the manual as well. Includes USB3 cable, upgraded and extended power supply, and copied driver/manual CD. We can guarantee that it works flawlessly on an up-to-date Windows 10 x64 system, but we can not make guarantees about other operating systems (because we did not test them.) We know that this has no support for Mac or linux. Do your due diligence if you are not 100% sure.
