The Parc can only do one thing that the Tact can do and that's to cut bass peaks (3 of them) it is an analog device that allows you to cut bass peaks where the room can not be fixed or accoustical treatments are not possible (WAF)
The Tact is a digital eq (put between digital source and DAC or preamp if DAC card is used) (it can also be used with analog input board but that is pretty good but not for the person with a 20k turntable rig (aka a Parc then becomes the right answer for those customers with TT's)graphic eq (2.0 = 12 bands, and the 2.0s/2.2x does 16 or 18 bands) that can cut and add(be careful and don't do this) plus what the 2.2x allows you to factor in the time delay between the main speakers and the sub(s) plus it can compensate for sidewall reflections and calculate/remove those wavs and adjust the timing in the digital domain. You can have EQ presets to tame 80's and 90's recording, boost midbass for a little Disco when the need arrise... etc... this is really cool feature that I use with music I love that is unlistenable on my system otherwise because of the poor recording.
The Tact has an automode that is quick and simple but doesn't really work... if you have patience and don't expect a stick the component in change you will get huge benifit's. This is one reason I haven't sold mine is that I know the potential is there if I can just sit down and work with it.
PS: Jeff - well stated... even though I only got it partially working that magic was truely addictive and it will be impossible to live without it later..
