TacT Room Correction System processors

Anybody have any experience they'd like to comment on with regards to the TacT digital room correction processor? The Tact is similar in function to Perpetual Technology's perpetually promised room correction processor. Any other digital room correction processors out there on the market? (Note -- a room correction processor is much more than a a garden-variety equalizer; it measures the speaker/room impulse response and applies its inverse to the signal, nullifying colorations and resonances imparted by the speaker and room. An RCS may be thought of as a "super"-equalizer in that equalizes both amplitude and delay at all frequencies in exceedingly small resolution bands far smaller than an EQ's typical 1/3 octave bands.)

i don't know the tact but it sounds like its "purpose" is similar to that intended for the accuphase dg-28. check it out on their website.

Sigtech makes several. I have not auditioned any, however.

I own the Sigtech and have hade the Tact unit in my room. I the room response (impluse and MLSSA) independently measured by and audio engineer. The Sigtech was far smoother. It also sounded better. I thing the Tact would be best for five channel HT. I have Dunlavy SC-v and the combination with the Sigtech is awesome.

Cornfedboy: thanks for the lead. The Accuphase DG-28 appears to be a very high quality automated graphic equalizer, but it doesn't look like it does true impulse response correction, just steady state frequency response correction (i.e., it adjusts amplitude but not phase of the speaker/room transfer function). As such it doesn't do a complete job of cleaning up transient effects such as room reflections and reverberations. Mouse and Pls1: thanks, the Sigtech Time Field correction processor is exactly the sort of thing I'm after. Unfortunately, their web site is a bit bolloxed up and the link to their home audio products is dead.
