 The top of the audio device has a big master volume knob, the device has a sturdy build (it took me 30mins to take it apart), and the volume knob is no exception. It feels solid.

 Nothing is on the bottom except a little switch. It can switch between USB 1.1 mode (U1) or USB 2.0 mode (U2). It helps optimize the device for different USB protocols, as noise through the USB input can cause noise in the audio output.

 This is a CMedia audio solution, which is common on Diamond Multimedia products. They offer great quality for a reasonable price. A CM6620 is the audio controller and the CM9882 is the codec (DAC/ADC) which features a 106dB SNR. The CM6620 is what connects to the USB on the computer, and it is spec is for USB 2.0 ports, so the USB mode selector switch on the bottom is for backwards compatibility with USB 1.0/1.1. The APA2306 is an amplifier for the headphone output. The cFeon EN39LV010 is a 1Mbit flash memory module for the controller. Audio controllers require memory access, and this means that this card needs its own memory since it’s not going to utilize the memory on the host computer.
