How can a PS Audio Perfect Wave DAC enhance my system?

Presumably the PS Audio DAC would sound better than the DAC of the Marantz.

I suggest auditioning one in your own system to find out.  If your ears don’t detect an improvement, your wallet will thank you

It is a nice sounding DAC.  Like everything else, you should audition it, if you have the opportunity to.  I believe there is a new version of it coming out soon, though I may be mistaken.

So if I was to use the PS Audio DAC in place of the DAC in my Marantz, wouldn't I just be improving the playback of my SACDs only?  My SACDs are a very small part of my digital collection on my A-500 NAS.  The PS Audio DAC is $8500 in my country which seems like a lot if all I am able to use it on is my SACD transport.  I'm hoping I've got this right.

Through the course of my reseach, it seems the DAC is best served when you have a music collection on a PC and the PC connected to the DAC by USB.  From what I can tell assuming I have this right, I don't fit this setup.

Thanks for the replies.

I would call PS Audio. They pride themselves on customer service, so they should be able to walk you through any issues. At least that’s what Paul claims. Can’t hurt. 

I have a PS Audio DSD DAC. It plays all the standard digital formats. If your Popcorn unit has a usb output that would make for an easy connection between it and the PS Audio DAC.
