I tried it too... APL Audio is at absolutely another level. It provides true results - almost ideal loudspeakers. ONLY LOUDSPEAKERS, not room acoustic. APL Audio is not bluffing about "perfect" room equalisation like some other companies do. You can not get ideal room acoustics for STEREO monitor system. Even theoretically - just at one listener's positions on mid axis (at 120 triangle point), all other positions in room have more or less but phasing problems. Room acoustics must be physically optimised. And loudspeaker placement and directivity must be physically optimised. Only at the end some very delicate room equalisation / fine-tuning can be done over all it.
