OP After being without my rig for 11 months due to a move, I am trying to dial in my system with horrible results at the new home.
1) Your ears became normal due to not listening hi-fi seriously for 11 months. In previous house, your ears were easily get into the immersive hearing mode which ignore harsh distortion noise from your system. Also, your ears might be in numb state due to harsh audio sounds and your ears were used it. Anyway it’s a good thing that your ears can hear any sound correctly now. Use this chance wisely.
2) Check out if there is any noise around your home from construction or water fountain. Any slight sound from in/outside can disturb the hi-fi sound. Human can’t hear a natural sound and un-natural sound together at same time. Ex.1) We say to noisy talking people in audio show "please be quiet. Let me hear the music." Ex.2) A dog barking outside can be irritation when listening music.
Try to hear your voice and speaker’s sound together. Say "hello" repeat with your speaker sounds.
