My pleasure.
I tested with only CD res files and above.
Roon sounded clearer and delivered with more authority than Plex regardless of source. Like a layer of haze removed and more to hear now. Yay!
Plex is also limited to CD resolution.
I need more time with Roon ARC still.
Plexamp is very good with Carplay.
I would account the high grade for Roon sound quality to its keen focus on music and a customer base of music lovers who want to get the most they can out of the music.
Whereas music is just a part of Plex. It’s focus is more audio/video with the prime focus on video.
Also Roon cost a good bit more than Plex. Don’t let that deter you if you are true music lover/audio enthusiast. It’s a very affordable high end audio component. You will be shocked to learn what you have been missing without it.
The Roon user experience is simply awesome It is like you are turned loose and can listen to anything in the world’s largest record store with plenty of tools provided to find your way around and discover new things about the music and the artists who make it. A music lovers paradise!
