There are a lot of good quality audio DAC’s(Digital to analog converter)on the market.
But a good inexpensive audio source is still difficult to find. Trends Audio developed the
Trends UD-10.1 USB Audio Converter as an external sound card. It has four digital
outputs (optical x1, coaxial x2 (RCA & BNC), AES/EBU x1, Trends UD-10 only) and a
headphone socket. It effectively isolates the interference from within the PC/Mac case,
caused by high frequency data signals, the switching mode power supply and the fan
motors.
The Trends UD-10.1 USB Audio Converter upgrades your PC/Mac to be a hi-end audio
source. Thanks to the high quality components and engineering the Trends UD-10.1
USB Audio Converter makes your PC/Mac into a high-end CD Player. Trends UD-10.1
USB Audio Converter and PC /Mac combination provides better sound quality, larger
storage capacity and a more user-friendly interface than most standard CD players.
The computer hard disk is far superior to a CD transport, no matter the speed, stability,
error correction or jitter reduction.
