Does this mean my device has a switching power supply inside it?

I just bought an iFi Zen Stream and I have a really high quality 12V LPS lying around so I powered it with that. (It says takes anywhere from 9V to 15V.) Sounds pretty good.

I suspected it had to regulate the 12V down to 5V because inside is an ARM chip.

I just noticed this verbiage on the iFi website: it contains a "synchronous 1.5MHz high-speed power supply controller for even great noise reduction and even less distortion."

Does that mean it's regulating the 12V down to 5 with a switching power supply? Arg. Maybe the LPS is providing no benefit if the first thing the circuitry does is inject 1.5 MHz noise into the whole chassis.

I have a SMPS that came with the Zen, so I'll try that too and see if there's any difference.
