Stand alone dac vs built in dac what's the better

Analog vs. Digital, Tubes vs. Solid State (see where we're going here?)......Which we be the way to go?(sic)

The nice thing about a separate DAC is you can buy a couple of CD players and use all of them with the DAC.
I use several five disc changers with my DAC.

Day or Night?

Which we be the way to go?

The biggest advantage to an outboard DAC is the delicate circuits are well away from the noisy transport mechanism. I purchased the best sounding player I could bring home and try regardless of price, but the sound was far more enchanting with a quality DAC.
Liz also has a good point, I also plug my I-Mac and video gear including Blue-Ray into the DAC.
