Yep, and a good sounding room will often gets people off the merry go round of gear buying and trading.
It is what happened to me....Any upgrade, even some good one i dream about, seems to me now a bit ridiculous like useless spending of money for some improvement, yes, but no more comparable to what my acoustics controls and treatment were, huge S.Q. increase, then....
Most well chosen good gear, the right speakers for the right room for sure, will create miracles only with acoustical embeddings treatment and controls.... Not so much without any in most room..... I am with you about that 100%....
My best wishes to you.....
