O.K. I'm Old/no Techie....how do I

If you want the very best result, then get a Mac Mini, even a used on on ebay. Put Pure Music on it and play back through a USB DAC. Like all DAC's USB DACs vary a lot in sound quality. The important thing with digital is to put your money where the clock is, that is the Master Clock. For CD's, this is in the Transport. In the case of the USB DAC, it's in the USB interface.

I heartily agree with the Mac Mini. Notebooks have LOTS of noise (primarily from the monitor) which screw up the sound. No depth, air...all confused...true of all notebooks.

Some DACs or players like the Oppo 95 allow you to play high rez FLAC from a USB thumb drive. This seems like a good solution for those of us who don't want to hook up a laptop to our stereos.
Also you can burn DVD-As from high rez files, although my old player has a hard time reading these. Also I think there's a 24/96 limit to DVD-A, so you might not be able to copy 24/192 files to a disc.

Stl114_NJ, you might try to make a DVD-A instead of copying the FLAC files. If you're using a Mac, there's a program called Burn that is free and can turn your high resolution files into a DVD-A. That way your Oppo won't have to try to interpret FLAC. And it should already understand DVD-A.
There's another program for PCs I've used successfully, but I forget what it's called. You can go to the Phish download site's FAQ (Phish make their shows downloadable in high rez FLAC) and there's a link there to a Turtle Beach (?) website that lists tools for making DVD-As.
