A whole new level of accuracy?
Would you like to take "your high-end system to a whole new level of accuracy, from high-fidelity to acoustic fidelity?" That's what the Trinnov ST2-HiFi loudspeaker/room optimizer ($6200) promises. And it looks like a pretty sophisticated device, measuring the impulse response of the loudspeaker in the room, analyzing the room modes, and automatically computing FIR and IIR filters to improve the dominance of direct sound over late reverberation, equalizing the response in both frequency and time domains. The ST-2-HiFi is supplied with a calibrated microphone array; once that's placed in the listening area, all you have to do is press a button and the ST-2-HiFi does the rest. Comparing the sound of a pair of Sonodyne amplified speakers before/after Trinnov ST-2-Hi-Fi correction, I noticed that the imaging became considerable more precise after the ST-2-Hi-Fi processing, and the bass seemed tighter.
