CD, SACD and DVD-A are all dying, so the smart move is to use what you have, the Macbook Pro and get a DAC and good USB interface or DAC with a good USB interface built-in. Notice that I didn't say a "good" DAC. The more important thing is the USB interface. This is where is makes most sense to put your money.
Both DAC configurations can be stellar, and even outperform your DC transport. However, you need to be ripping with XLD, not iTunes and to AIFF format, not ALAC. Playback should be a combination of iTunes and Amarra or Pure Music. You will find once you do these things that the SQ is improved dramatically.
There are also some things that you can do to improve the Macbook Pro:
