I'm not sure what you mean by "losing the in-concert feeling."
The room equalization software available in most modern receivers is intended to make the sound you hear coming from your speakers much more accurate than it would be without the equalization. It tries to compensate for infelicities in your speakers and the listening room. Of course, you should still use the highest quality speakers you can afford and apply appropriate treatments to the room to eliminate sound reflections, low frequency modes and other sources of audio degradation.
