How important is the transport when using a DAC?

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.
Regards,

One thing I learned to avoid (and dismiss if others make them) in audio is making categorical statements about the inherent superiority of one technology over another.

It is probably possible to build a fine sounding DAC using both a linear and a switching powersupply.

Ed - Ive tried several linears and none of them work well for digital. Analog maybe. Even LI batteries with ultracaps in parallel are not as good.

Until you have heard a good switcher/series regulator, you cant possibly understand. Believe me, the difference is incredible. There are none like this available on the market yet BTW.

Steve, the best digital I have heard (by a mile) is the MSB series IV. A lot of people that have listened to every 5 figure DAC under the sun concurr. It uses a linear powersupply.

May be a better mousetrap using your switcher/series regulators is just around the corner. Who knows. Technology moves on.

For now, all I can say that if the best sounding DAC money can buy uses a linear powersupply, it is premature to write it off as technology unsuiteable for digital applications.

Did I just read (again) that a power supply is better than a chemical battery to provide DC to a component?

This sounds like the Naim dealer who insisted two car batteries would not run a preamp. The 24 volts would not be "clean enough" and the performance would suffer.

Sorry to sound sarcastic...and I am not claiming to be the end all guru here, but a battery is perfect DC, is it not?
Especially for a preamp or DAC/CD player application which is essentially a stable load.
