I think it depends on the maker of the CDP or SACD/DVD player. The Pioneer Elite DV09 and the Pioneer PD-D9 J SACD players were well built transports that when I used with an outboard DAC made good music in my systems. When I had a Marantz CD 5003 or an Emotiva ERC-1 and used them as transports to an outboard DAC they held up to the Pioneer SACD and DVD players I had. The only time I had a problem with a DVD or CD transport was when I was using a Memorex DVD player from RadioShack that had a uber thin disc tray.
