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.
