CIAUDIO VDC-9.0 Powering Wadia 170I Transport

It depends on the rest of your system. In some transpartent systems you can hear the difference (and it's worth it), in other systems you can't hear it...

Too bad there has not been more responses to this question. I'd also like to hear some opinions from owners of the CIAudio VDC-9.0 and Wadia 170i.

Cleaner, clearer images from a darker background. Have had the set up for about a year and a half. Definite improvement over the wall wart.

I've had the Wadia over a year and added the VDC-9 a couple of weeks ago. I think the power supply addition did more to upgrade the sound of my system when playing the iPod than virtually any single component change I've experienced during my 50 years of audio hobby. I'm hearing things that I didn't know were on the CDs that I ripped to Apple Lossless. The difference for me was so great that I seldom listen to my CD players anymore (McIntosh MVP871 and Linn Akurate CD). My electronics are current model McIntosh and speakers are also McIntosh (XR200).
