@woofman74 @ghdprentice @jerryg123 Yes, ear cleaning is a regular maintenance item for me.
@chowkwan Grills are off to see the impact. I read quite an in depth article about this on audioholics which claims that the frame is the biggest factor on sound quality. My speakers have a grill which connects to the sides of the speakers, so the effect from the frame is minor.
@waytoomuchstuff Since the grills were off, I found that the 10 screws on each speaker that were holding the drivers did accept a bit of tightening. Good idea! I already fixed a previous issue with a loose RCA connector.
@paradisecom I don’t actually notice that my room is live - is there an easy way to test it without using a microphone? I have quite a few bookshelves along the walls, and other similar things around the room, so there are a lot of small surfaces. I’ll add a rug soon.
@mapman Based on the comments made I now see that my audio is set up for near field listening. I’ll try to find tweaks that apply to that situation. I’m comfortable taking the time and having the patience to move speakers a bit at a time to try to find the sweet spot.
