Most youtube ripping websites reduce the sound quality of a song to 128kbps. The resulting mp3 will not sound as good as a new mp3 from say iTunes or bandcamp. While the difference in quality isn’t night and day, you will definitely notice it on a good sound system. Try it. Get a fav track from bandcamp, then obtain the same song via youtube to rip.
Best of luck. Keep those records spinning.
