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

I would like to thank everyone who has contributed and helped me with my decision to add a DAC to my system.  My window of opportunity was closing so I went ahead and purchased the PS Audio Perfect Wave DAC Mk II with Bridge.  I am currently waiting for shipment.

If no one objects, could we use this same thread while I look for your advise on integrating this into my setup?

I plan to keep my McIntosh C48 preamp in my system.  Knowing the PSA has a bridge card will make it easy to stream my digital files on my Popcorn Hour A-500.

The C48 has several digital inputs apart from the conventional RCA inputs.  There is a USB, optical, and cable input.  Also, there is an XLR balanced input and I believe you can take something like PHONO1 or PHONO2 and swap that source to balanced input.  I will check the manual.

I would like to run my Marantz SACD through the PSA too.  The only digital outputs on this are optical and coax.  I just learned the optical connection is limited in its sampling rate.  

In advance, thanks to everyone.

Research if you can configure the PS Audio to read the music on the popcorn HDD via network. You should be able to specify the ip address and folder of the popcorn in the PS Audio set up. I hope it’s possible. That would eliminate any format limitations associated with coax interface. 

I am quite optimistic that will not be an issue with the PSA bridge as as the Popcorn Hour A-500 supports DLNA (UPNP) and I can already see the files across my network on a variety of devices.  Just being able to stream across the LAN makes everything a lot easier.  My music file are mostly FLAC and DSF.

My only other digital source is my SACD and to be honest, I don't use it that much.  My hi-res SACD collection is not large and I notice the selection and prices on Discogs are less attractive recently.

UPDATE:

I took my PerfectWave Mk II DAC and upgraded it to a DirectStream Sr. with a Bridge II card.  I retired my A-500 music server and got a good deal on an Aurender N100H 4GB.  I'm back in business and the DSD sounds amazing.  Thanks for all the input.
