All those who are suggesting that the room needs to be lively miss the point completely. The need is to reproduce exactly what is recorded, not what is distorted by room interaction. A dead room does NOT interfere with the signal coming from the speakers. A live room distorts the signals by creating echoes and resonances that change the tonal balance and the sound coming from the driver surfaces.
Using near field speakers and sitting a couple of feet away from the speakers eliminates almost all the room effect. That’s the real beauty of that kind of design.
It's not hard to remove the room from the reproduced music. Just fill the room with artificial ficus trees, 5' to 6' in height. They are excellent diffusers and are inexpensive when compared to "audiophile" room solutions.
