TACT digital corrections preamps?

Just took delivery earlier this week. It was pretty easy to setup and get running. My immediate reaction is that it works as advertised, however, it appears that it will take a fair amount of work to optimize it in my system. Tact is definitely not a plug in and play product.

I have the Tact 2.0 and overall I am very pleased with its performance. All the above positive comments are true. I only have two real issues with the product. First, the software is Windows based (I'm a Mac maniac) and not very intuitive. It's very powerful, but you wouldn't really know it from going through the owner's manual. Second, it's very hard to make comparisons using the bypass mode. As part of the room correction process the Tact changes the overall volume so when you hit bypass you really can't make a fair comparison.

If you have say, $10-15k invested in your equipment, then there are probably more effective ways to upgrade your system, but if you're up in the $30k plus range, then I would strongly recommend it, even if you don't think you need room correction. The positive influence on sounstage and imaging is that great.
