Tact 2.2XP for room correction "proof of concept"

I am currently integrating a 2.2 and 5.2 system using an analog MCH player as source, analog MCH preamp, outboard DAC, 2 channel preamp with bypass, external cross-over and bass EQ unit. In summary, lots of boxes, a cabling nightmare and no room correction other than for the subs. I use my system 90% of the time in 2.2 mode.

I also own a Casablanca III, and Theta will be releasing Dirac room EQ later this summer. Upgrading my CBIII would allow me to move from MCH analog to HDMI based, and allow me to do bass management and EQ in the Casablanca III processor, dramatically simplifying my system in the process. However upgrading my CBIII to HD Dirac level would be a significant outlay, so I want to test the room correction waters before committing a substantial funds.

So I am thinking of getting a used Tact 2.2XP to see if room correction (and better crossover filtering) helps my system, and if does move to CBIII HD Dirac when it is released. Has anyone used a Tact based 2.2 system, and compared this with ffect of room correction in a very good multi-channel system playing in 2.2 mode? In other words, can Tact correction be used as a good proxy for what to expect from a multi channel SSP?

Kal, I plan to do this by taking out my SVS Bass EQ unit and my external analog crossover, and get a Tact 2.2XP unit (digital in/out version) to do my cross-over filtering and room EQ - all in the digital domain. I will still use 2 external DACs; one for my 2 subs and one for my mains.

The Tact 2.2XP will not do anything for my multi-channel 5.2 system (which continues to be all analog), but if I like the digital Tact route for 2.2, I will probably make the leap of faith Theta Dirac Live will work equally well in 2.2 and 5.2 mode, and eventually go down this path if/when Theta ships.

OK. I suspect that the Theta/Dirac will be superior but that's all to the good. Too bad there are no rental units for these things.

Too bad indeed, alhhough I have had good luck picking up used stuff on audiogon and resell without a loss for these type of expiriments. I'll keep my eyes open, and if all else fails I may even get a new one (at a healthy discount) and just take the hit if/when I switch to Theta/Dirac.

If you are going used, consider also units from Trinnov and DEQX.

Thanks - I checked and the Trinnov ST2 and the DEQX HPD-3 look very intriguing. I need a bit more looking into functionality and specs, but I may cast the net wider and pick up the first reasonably priced unit of any of these three contenders that shows up.
