In my secondary system in my gym I have a Yamaha receiver driving 4 speakers (pair of Tannoys and a pair of PSBs) and a subwoofer. The source is my PC connected via a soundcard to the Yamaha. It actually sounds not too bad, but I'm sure it could be MUCH better.
Worth this be a worthy upgrade from using the soundcard onboard the PC?
The price is US$149 for Trends UD-10 and US$20 for the Trends Charge Kit. If you are planning to use PC for better audio experience than going for individual Hi-fi music system (better buy speakers for PC than buy audio systems with surround system features). Trends Audio UD-10 + Trends TA-10 Amp will be the good choice
