Modi is the most advanced USB DAC under $100 that is made in the USA. With a C-Media CM6631 USB 2.0 asynchronous input receiver and 24-bit AKM4396 DAC coupled to an active filter output stage, Modi is ideal for a computer-centered audio system.USB Powered, No DriversModi plugs into virtually any computer-Windows or Mac-and requires no drivers to deliver great sound, up to 24/96 sampling rates. It features asynchronous transfer with individual crystal oscillators for the 44.1 and 48k sampling rates, and uses the USB Audio 1.0 standard over USB 2.0, and is powered by the USB port.24-Bit AKM4396 DACModi uses the 24-bit AKM4396 DAC with switched-capacitor filtering and a high-quality active filter section with excellent line-driving capability. Yeah, we know, engineerese is a disease. What this means is that it uses one of the highest-performance DAC ICs out there, and it will comfortably drive long cables. You can easily hide Modi behind your computer and run long RCAs to your main audio system.Made in USABy "made in USA," we mean made in USA. The vast majority of the total production cost of Modi-chassis, boards, assembly, etc-goes to US companies. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley.
