Using a PS Audio Perfectwave Dac as a music server

The PWD is not a server it's just a DAC. You would need to buy a data storage unit and a controller to have a server system.

A laptop computer with the appropriate software program plugged into the PWD could serve both functions. A Music Vault (do a search they're sold on Audiogon) with an iphone or ipad would work if you have a home wireless network.

These aren't the only possibilities. I don't have a server system and I'm not very knowledgeable about them so there are lots of other options out there. Peruse the PC Audio forum for more information.

Thanks Tomcy6. I knew the hard drive would have to be external (I didn't make that clear), but I didn't know that you needed a separate controller. And on top of that you need a bridge, I believe. Sounds less simple than we'd like it to be...

Your iPhone or iTouch will work as the controller - in fact, they are recommended. The software that you need for the controller is only $9.99 via iTunes and is a simple download. If you already own the PWD, then you simply must buy the Bridge - even if you own the PWT too.
