If you have a nice system why do you really need room treatments?

@timkeough1964 sums it up well.

Something is really off with OP comments. He has started 225 posts, and has had 897 replies, in the past 3 1/2 years. Somehow conveying details of his superior system and the room it is in is somehow problematic? Hmmmm…. 

It is not insensitive or unfairly treating someone with a disability to expect the same conduct as that of anyone else on this forum.  The OP has been asked repeatedly to describe his system.  A reasonable request, yet no response.  There is too much history of this OP starting a thread with a particular premise, then arguing both sides either in the same thread or another different thread.  

Too much evidence of no meaningful contribution by the OP, only stirring the pot until everyone finally realizes there is nothing new of value being offered.  OP contributions are pretty much, "Yeah, but . . ., Yeah, but . . . , Yeah, but . . .".

Sounds like a conversation with my wife.
Ow. She just hit me.

The best system in the world can not fix bad acoustics. If the room is bad, chances are no matter what you put in it, will not sound good, or better said, not live up to its potential.

A great sounding room is a huge head start. Good sounding rooms are more than just good sounding for the stereo system. They’re pleasant rooms to be in, to talk in, to sing or play an instrument in. That’s the good news. A properly treated room just sounds nice all around, for all uses.

If you have a room that’s edgy sounding to talk in, you can hear your foot steps cavernously echoing off the walls and ceiling, how much better can you possibly expect the stereo to sound? This kind of sound can occur in well furnished rooms that have high ceilings because there can be a lot of bare wall space above the furnishing zone.

The bass is one area that might go unnoticed in daily activity because you are not necessarily making bass sounds that appear in music. I think that’s why bass treatments and equalization can still be necessary for a stereo system in an otherwise very nice sounding room that’s simply been treated with furnishings.

Another issue is symmetry and stereo imaging. The 2 speaker arrangement is a fragile thing in terms of imaging. Some strategically placed treatments on top of the standard furnishings can go a long ways to improve imaging. An imaging treatment can be as  simple as an angled flat surface. I've got one of those in my office right now because there's a wall close to my right and not to my left. a 2' x 2' angled flat wooden panel centers the imaging for me.

Oh yes. Put your stereo at any price into an untreated gym and play it really loud. If you enjoy it that way, more power to you.

I can attest to the fact that it is not fun to listen to a stereo in an untreated gym. I've been working on mine for a couple  of months now &  it's getting to the point where I'm happy. Just a few more tweaks.
