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

Having just experienced this first hand: you need to treat your room.

To be more accurate, you need to know how to determine AND hear HOW your room is coloring altering or outright changing sound, sound stage, frequencies, etc.  This should be a testing process that people go thru when setting up their components and their speakers in their listening area. 

I went thru this with my step father, who has been an audiophile my whole life.  His incredible system and amazing top notch speakers literally sounded AND measured horribly in the room he had set up.  To him though, it sounded amazing and never heard anything better.  To me, it was literally unlistenable....and oddly to him, it was unlistenable as well he just didn't realize it (never listens above 65db, only listened for an hour or two).

ronboco,

actually you're wrong on that one there is a video from the owner of the company showing that when you stamp on concrete you get just as much vibration coming through the floor just at a different frequency then from wood so you would benefit just as much, I was shocked when he stamped on the floor and the little seismographs that were on the speakers started jumping up and down like crazy with the needle I didn't think concrete would transmit anything so I think you should give them a try like I said if you don't like them you can send them back and they give you your money back no one has ever sent a pair back yet.

@zuesman So true about concrete. I remember seeing Tangerine Dream in concert, in 1986-7, at a small venue in Chicago. It was standing room only, on concrete floors. I remember the bass reverberating in my feet, from the concrete then feeling it in my body. It was one of the loudest concerts I have been to.

 My belief is that you should be able to discern the quality system regardless of acoustical treatments.  The problem is it's very difficult to play around with things given the massive weight of all the equipment. Once you get everything in place it's very difficult for you to swap in and out different options and you're pretty much stuck with what you've got.

It's not rocket science, if you have an echo room get a rug, buy some furniture and maybe stick an absorption panel on one of the walls and corners. Unfortunately most people are hard-pressed to put acoustical crap on their ceilings. Getting rid of reverbs is important and size of the room is important. If you've got a very large room you're gonna need a lot of power to fill it with sound and of course speakers can handle it. Again it's not rocket science. And if you need special gear to test the environment so you can feel more confident that's a problem, you should be able to discern it all by yourself.
