How important is the transport when using a DAC?

Hello,

I've been thinking lately, if my transport is extreme low-end, is having a nice DAC a waste of time? In other words, if I am using a $60 Sony DVD/CD player to deliver the digital signal through a coax cable to my Arcam r-Dac, is that not doing it justice? Do you recommend I upgrade my transport to better meet the quality of the DAC or does it not matter?

Thanks!

The linear powersupply in the Oppo 105 is only used for the analog section. However, some manufacturers (Ayre DX-5 - Theta Compli 3D) have put linear PSs in Oppo based players for the digital section, apparently with good results.

That's debatable. Compared to what?

Charles - there is a big difference between a switcher and a good quality switcher followed by a fast discrete linear regulator.

The ($4000) Theta Compli 3D is basically an Oppo 93 with a Theta faceplate and a linear powersupply and all the analog circuits ripped out. According to its owners it sounds quite a bit better than the Oppo 93.

I personally also have a linear powersupply in my Oppo 93, but never did an A/B comparison with the old powersupply.

MSB is another example I've heard several times recently that utilizes a quality linear PS and provides that natural realistic sound with exceptional tonality. I like to know what digital sources have this desirable presentation with a nonlinear PS.
