Most rooms don’t need acoustical treatment.

Jumia- All the variations in recording qualities that endlessly frustrate?  You mean all the good bad and the ugly of trying to record and recreate a real live music event?

Though an interesting premise that acoustic treatments are poppycock, I find the OP to be that instead, and rolling this into the snake oil channel is just ignorant.

My experience was the exact opposite and by adding a few treatments to my room and a throw rug my audio enjoyment was increased by 10 fold. 
Now I do thing is all works together and is part of the formula in the search for acoustic perfection, a goal we will never achieve. Treatments, furniture, cables and yes even fuses all play a part, but many not in every system or listening room.

Just go into this hobby or obsession with an open mind. A closed mind limits your friends, audience, and enjoyment and makes you a lonely and angry. 
 

" These rooms don’t really have a need for treatment. It’s snake oil, voodoo science. "
acoustics is literally physics. how sound waves interact with your room is well understood by now and critical for good sound. True with big operas and theaters, just as true with your small room

Lone mountain, live music is what it is, and sometimes really great sq.

i am talking about crappy studio efforts. Accoustic treatments will improve crappy recordings, but wont make all crappiness go away.

I haven't read the whole thread for a long time. but since I'm an acoustic engineer, I can only say one thing to the OP.
how stupid is ignorance
