How important is the transport when using a DAC?

I don't believe for a minute that linear power supplies are too slow for digital.The lastest ModWright 105 OPPO and the Yamamoto YDA-1 DAC (two fine examples) use well built and implemented linear power supplies. If the criteria and goal is pure natural music reproduction and involving musically and realism, I'd put these two excellent digital components up against any alternative with switching PS in terms of actual sound quality. What are some examples of these newer and better switching PS digital components? I'd like to hear them and compare.
Regards,

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.
