Sony CDP-XA7ES as Transport ???


Just how good is the Sony CDP-XA7ES when used as a transport compared to a quality dedicated transport? The actual transport mechanism is top drawer (pun intended). But how much of this translates (sic) to the digital output?

Related but separate question: Would changing the RCA digital output jack to a BNC make more than a marginal difference?

Thanks for your input!
