Dvd player or C D transport with a DAC ?

Dollar for dollar,I have heard that a DVD player transport used with a DAC will out perform a CD transport and that the best CD transports can outperform the best DVD players used as a transport at considerable more cost.

I am considering replacing my Cal Audio Delta transport with a Denon DVD 1200 player($420).Any feedback from those that have compared the 2 formats as a transport.Thanks !
