OP... don't get rid of your Astral. Someone else mentioned it already...but it's a lack.of reference that has you second guessing.
EQ (parametric EQ) is a good tool. It can help you fine tune the sound of the IEM to your liking. But...the IEM should sound good to you out of the box. HD550...hmmm... just go for the legend. Save for the HD600.
I wrote down my experiences and things I learned as a beginner [Posted here](https://www.reddit.com/r/iems/s/u2D7CWFQw9) Go and find all the reviews you can on the Astral. Listen to the terminologies and try to associate what you hear from the Astral. Then pick up a budget set or two (if you want to learn) watch those reviews from the same reviewer. See if you can hear what they are hearing...and establish a frame of reference. Hope that makes sense.
Outside of that...you picked a really good IEM. Stick with it. HD
