My reference recordings are of acoustic instruments in reverberant space… mostly churches… The first distortion is… microphone selection…
Not every reverberant space created equal… indeed listening seat…
Room treatment for speakers is a science and black art…often overdone in those sterile audiophile rooms… don’t get me started by the tank trap forest of amplifiers blocking the TT on a massive rack planted between the speakers….
Don’t neglect diffusion… my favorite are from Arnold at Core Audio Designs…
