I'm glad I came across this forum, because I'm sure someone will have a good answer to the following question. As we're all aware, there are $99 5 Disc Sony CD players out in the market place that are dirt cheap and there are units from high end manufacturers that run well over a $1,000. My question is this. . . If you are using the player strictly for data extraction, meaning that you're running an optical out to your receiver, then what possible difference is there between players??? For example, I'm using a Sony 5 Disc with an optical out running to my H/K 525, so I'm clearly utilizing my H/K DAC's, not the Sony's. The Sony is simply pulling data from the disc and communicating that info to the receiver so it can do all of the processing and digital to analog converting. I've thought about this for some time now and can't come up with a benefit that a high end player would provide in this scenario.
