All rooms have acoustics and each is different.
If you want to hear what your gear sounds like without room acoustics set your speakers up outside.
Years ago I set up my Ohm Walsh speakers cranking off a Tandberg tr2080 receiver outside on a porch of a rural Kentucky farmhouse for an outside party. Wowsa!!!! THe best sound I ever got out of system up to that time by a longshot even 40 yards away. Crazy Horse and others were jamming like live both loud and clear!.
