I noted the weight of the Onkyo C7030 is at least twice as much as the NAD and Yamaha CD players. Does the Onkyo use a different power supply? Can't imagine why there is such a disparity in weight. Also wondering if the NAD and Yamaha units use a newer type of power supply which would result in less weight in the unit?
Buy it where you can get the extended warranty I think max is 4 years. Mine died shortly after the factory warranty expired and mine was sensitive to vibration as in walking to the extreme.The only hesitation I have at the moment with the Onkyo is the fact that I've read a lot of reviews where people state it skips a lot. Not all reviews of course but a fairly large number. Sound quality is excellent otherwise. If I buy new then at least I can return it and replace it.
Sam and Cat. Where did you purchase your used players? Bay? Craigslist? I will at least give a look to see what is available. Want to have a good DAC in the unit since older CD players with older DAC's don't seem to sound as good as newer models with newer DAC's on board. At least that has been the case with my ears when comparing older units that I had to newer models.
