ok we just did a blind test. my daughter scrambled up four playings of "this beautiful day" -- cd quality and hi res, for my wife and me. We are both over 50, and my wife is not nearly as into music as I am. Absolutely no question -- we said hi res, cd quality, cd quality, hi res. Huge difference. My wife said "our stereo has never sounded so good." Try it yourself. You don't need a ponoplayer to play the flac files, just download the program pono musicworld. The program is free, the flac files will cost you less than a couple of bucks each.
NO IT'S "AURAL BUTT SNIFFING". I DON'T APPRECAITE QUALITY PRESERVATION ON ANYONE'S PART, I JUST LISTEN TO 64KBPS WMA FILES AND NEVER TAKE SHOWERZ
