Any experience with 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

This has been discussed in multiple threads over the last year. I own a Sigtech, use it with tubes and wouldn't live without it. Try the following threads:

I heard the Tact at the Stereophile show in NYC today. I was very impressed by the demonstration. The others in the room were also. Music was demonstrated with the correction and without. Wow! The most noticable difference was the bass. Any muddiness was gone with correction. The drivers start and stop enabling you to hear between the notes in a way I have never heard. Vocals were more focused. They demonstrated with a Tact digital amp. In my opinion, it was by far, the most impressive exhibit at the show today. It is a preamp amd comes with the option of a DAC, which is connected after it, and before the amp. Retail is $3000, $3600 with the DAC. Considering the elimination of the need for a preamp, it seems like a great deal.
