I have just setup a home media server. Something I have been wanting to do for some time. I am using Plex on a intel Atom 3735 mini pc with an external hdd. My home theater is a Samsung smart tv (w/ plex app) A Yahama RX-V663 receiver (want to upgrade) and B&W M1 speakers. I love to listen to my music liberary but being as the library has been build from various sources (download, cd rip, itunes) and over 20 years, lots of my mp3's quality sucks. Sorry for all the fluff but here is the actual questions:
How do I make my mp3's sound better? HD conversion (what ever that could mean), Mastering, Etc. I want the quality of audio to sound better, I dont care what the file is as long as it sounds good.
I thought about iTunes match but I dont think they will let me download their files. Thanks in advance for all the help
