What is more important? Room engineering, amp or speakers?
Your listening space is the most important. Then speakers and the other components.
This is my experience. The room itself is the most important. My living room is unlistenable, and so large and oddly shaped that room treatment isn’t feasible. No matter what speaker I put in it, it sounds like shit. I’ve given up and use headphones to watch TV there.
In my opinion, in a more typical room, one well damped by furniture, carpets, bookshelves etc., the speakers will be dominant. If the room is sparsely furnished and floors and walls are bare, then room treatment can dominate. The amp is a distant third and will only have a significantly negative impact if it’s being driven into distortion because it’s struggling to drive difficult speakers.
I’ve tried my TVs built-in speaker, vintage Polk’s 5jr’s and RTA 12’s, and new KEF Q250’s. All three with and without my vintage Polk center channel. The current receiver is a Yamaha TSR-7860. It has room correction. I tried with and without. It doesn’t help at all. Also tried my vintage Marantz quad receiver, and my NAD 3020. Every setup had the same problem of sounding so muddy in the upper mids that dialogue is completely unintelligible and music is unlistenable.
Room ~ Speakers > Amp.
None of the above. Wallet is the most important.
it’s a ridiculous conversation.
