There is nothing inherently "pretentious" about choosing separate transport and DAC over a CDP. For many of us,the former route is a superior choice due to what we hear ...
Of course. It's also more practical because you can replace the transport as it ages out (they are all subject to mechanical as well as laser wear) without replacing the DAC. Or, you can upgrade your DAC without replacing the transport. Typically in audio, I prefer separate components for flexibility.
