Spring 2021: Added photos with mixture of deflectors (boards), diffusors (GIK, bookshelves), absorbers (ATS, GIK), and bass traps (Real Traps), along with some DIY (utilizing OC 703, OC R38 pink fluffy).
Got this from your system page. Did the problem start before or after this change? I fought brightness for years but never with Steely Dan & especially Aja. Is your streaming really HD? Sometimes HD is still lossy IE 320 kbps. Something is amiss and I doubt it is SD recordings. Good luck finding it
BTW, the brick wall throws up big red flags to me. hard surfaces bring about brightness.. But its still peculiar that everything else sounds good. Quite the mystery which usually means it's a simple fix
