Hi mapman, up until a few months ago I would pretty much agree with you. But if I listened to vinyl for a few days and then went back to digital I would hear a difference in PRAT. It was clear that vinyl was much better. About a month after I got my new DAC I decided to spin some CDs one evening on my CD transport rather than listen through the music server. I was spellbound all evening. The music was amazing. I played 5 CDs straight through not skipping a single track. I couldn’t understand why it was so different from my NUC based music server running Roon/Rock. The next day I did some A/B between the music server and transport. I had my son listen too. The CDs and the FLAC files sounded very close to the same. Now I was confused. So I listened to several songs on CD and then switched to the music server and now I could hear the difference in PRAT. That lead me to try a better music server. Got one in on a 30 day trial. It not only sounds way better streaming but now has PRAT like my vinyl rig, like the CD transport.
I had no idea what PRAT was 30 years ago until another audiophile buddy came over to hear my rig one time. He told me that my turntable had terrible PRAT. He was a big Linn Turntable fan. I started to understand why some turntables that I heard just seemed to let the music flow where others just made sound. I made some mods to my turntable and back then and got some surprising improvement. It has been hit and miss over the years but very happy with my current turntable with respect to PRAT and other things.
