Any experience with room correction ?

I have not used the Sigtech or the Tact, but do use a McIntosh room equalizer. I have the same concern you do, and have biamped the system and use the correction only on the bass (below 125Hz). I want to get a better EQ for the bass, while the Mc is good--it's not at the level I would like. I am speaking with a company that makes professional studio gear and trying to get them to make a parametric EQ specifically designed for this application. It will be extremely low noise as it will be designed as a high end piece of gear with components used for professional recording studios, and it will be analog, so there is no A/D or D/A conversion. Also, it should cost well below 1/2 of the TACT RCS 2.0. Well, they have not yet agreed to build it, but I would be interested in hearing from others if something like this would be useful to enough people that I can convince them that this project is worth their while. Also, I'm not associated with this company, other than a friend of mine owns it. I want to buy one of these things for myself--I have nothing else to gain from it. Siddh, I don't know if I've helped you much, but I would be interested in your response to this and anyone else out there interested in room correction.

Thanks Abstract,

As with all component additions, the actual benefits or declination within the system, may only be realized with the the piece in line. All else is theory. The possibility of adding an analog design does ique my interest. If you are convincing in spurring your friend's company into manufacturing a prototype, please let me know. I would gladly audition, with feedback, with intent to purchase.

Both the Sigtech and the Tact do all their corrections in the digital domain. There is virtually no degradation in the signal.BTW They really work.
Good Luck
