Ive been wondering about upgrading my DenonCd player model # DCD 810. On the front panel it has 2DAC / 4Times over sampling Double Super Linear Converter. I bought this new in 1988 $500.00, its always been a good cd player to me . Since ive really gotten into my music , i used a test cd one night that plays a track for a test of noise i believe. Any way your instructed to turn your volume up as the sound track is going down until you reach max volume . As the sound track is going down almost completely, you can hear a slight distortion in the left side . I have did all my process of eliminations, narrowing it down to the cd player. I used my dvd player from another room and the noise isnt there! So question , is this Denon worth repairing or is it time to move forward? Thanks for any input Chris[*-)]
