I have a 6 year old Sony 5 disc changer, and the one thing it does best is the error correction. TO SIEBERT: All changers have at least a Toslink connection, so you could get a toslink optical cable and connect a Musical Fidelity X-DAC (I'll be putting mine up for sale soon). OR, you could use an MSB Link. Or, for more money and best performance value, the Bel Canto DAC-1 (www.belcantodesign.com). A DAC IS AN EXTERNAL digital-to-analog converter that takes the digital signal from a CD or DVD player, or dedicated transport, and converts it to analog to run to your receiver or preamplifier's line level inputs. YOU DEFINITELY NEED TO READ "THE COMPLETE GUIDE TO HIGHEND AUDIO". Find a dealer or friend who'll let you borrow a copy for a while, or else buy one. If you live near a large metropolitan area, I'm sure you could find a copy at the used book store. And try to borrow some old copies of Stereophile magazine, and then eventually think about subscribing (although they've seen better days). THE BEST ARTICLE I'VE EVER READ ON DIGITAL IS ROBERT HARLEY'S ORIGINAL REVIEW OF THE WADIA 27 DAC, in a 1996 issue of Stereophile. HE WAS REALLY AT HIS PEAK WITH SPHL IN THE YEARS AFTER HE WROTE "THE GUIDE".
