How to start streaming

USB from computer to DAC would be cheapest and easiest way. 

Or there are many wireless audio or media streaming devices that could be used.  Just pick one.  

Plex is a very good multimedia streaming software system that runs on most any device and supports CD resolution digital streaming of music files.   Look it up. Server and web site client is free.  Apps for Smartphone or tablet are just a few bucks.  Need to be a little computer savy to set it up though perhaps.  

2psyop:  I have downloaded many, many files for the purpose of creating CDs of them to play on my system.
Just the opposite of converting CDs to files.

@rvpiano,

What is the resolution of your stored files? If you own a iPhone/iPad I would recommend Apple AirPort Express and a 3.5mm/ optical cable setup.

If your files are at least cd quality (16bit/44.1khz) resolution or higher then you should look into a dedicated streamer like Bluesound Node,

You can use digital coax or Toslink cable from Node to Gungnir DAC. Or use RCA out from Node to your preamp/processor to bypass Gungnir DAC. Just connect your NAS drive to Node via USB cable and start listening to your stored files. I believe Node comes with all the cables you would need and their customer service is top notch.

The Node setup is very easy, will yield better sound over PC and offers many options to stream music like Tidal, Spotify (with paid subscription).

Hope this helps!

Lalitk,

Thank you.  Your post is most helpful.
All of my files are .flac files and very many are 24/96 and 24/192 resolution.

Mainly what I want to do is access my files remotely from my iPad and/or PC
and play them on my system.
