Pitched up an audio file and now it sounds shaky?

One file is the instrumental of Hozier’s Angel of Small Death and the Codeine Scene, and the other is a pitched up version. I pitched the instrumental from G#/Ab to A (I dont remember the specs before the change) to get it to match and while the pitch technically matches, I cant figure out why the audio is so garbled. I’m not too positive on what I can and cant post link/file wise as I created an account to ask for the help.

I make sure both audio files were playing at 44100hz but the one I pitched sounds too twangy and shaky, slightly echoed if that makes any sense. If anyone knows better than I and can guide me on anything I can post to help y’all understand what im hearing that would be much appreciated!
