Talk about audio quality...This Classic Denon DA-500 has the fabulous PCM1702 digital chip which makes this a very musical and analog-like sounding DAC...A little research on the web and you'll understand why this chip is so sought after...This low mileage unit is completely stock and with some modification (Again,a lot of info on the web) this baby will sing even sweeter! The face is in excellent condition with some scratches on the top plate...I'll be happy to answer any questions...Buy with confidence!
