Digital room correction, any recommendations?

Hi,
I happen to be local to the US Trinnov rep (and partner in the company) and borrowed a unit from him. Curt is very helpful and knowledgeable. I picked up my ST2 Pro today and will run it through its paces this weekend and take notes. Seeing as no one has reviewed the Trinnov in depth I may write something up. What I like is that the unit shows both the frequency and time domain response and corrects for each separately (or you can make the corrections by creating your own target curves).

The Trinnov ST2 Pro (there will be a consumer version with RCA SPDIF and Toslink digital I/O and RCA analog I/O) can process 4 channels although there are 8 channels' worth of inputs, 4 XLR RCA and 4 AEX/EBU channels. I believe you can mix and match - I will be testing this with my Oppo player to see if I can get the LPCM left right stereo in via digital and the center and subwoofer in via analog (using XLR adapters since the Oppo outputs are RCA).

You can also biamp and use the output (4 channels) with the software based crossover.

Feel free to ask me more pointed questions. I almost went for the Accuphase DG38 earlier this year but feel that the Trinnov approach seem quite solid and innovative. For one, the Trinnov people seem to have made significant inroads in professional cinemas and on the professional level, which lends some credibility to their approach. The well known US home theater component company ADA also will be releasing their version of a RC unit based on Trinnov technology.

I corresponded with the DEQX people, and I'm impressed with the attention they gave to my questions. They even researched my speakers, to determine whether the active crossover feature might be of benefit. I was surprised to learn that the external active crossover feature can be implemented without bypassing the internal passive crossover- they can be made to work together in the interest of reducing driver distortion. Also, their unit has digital ins and outs, so it meets Acousticfrontier's criteria listed earlier in this thread.

I realize this is a really old thread, but Psag's post above using an active crossover to pass through a passive crossover would take away the advantages of going active in the first place?

I've had the DEQX in my system now for several years. We decided not to implement the active crossover feature, which would have required opening the speaker and disconnecting the passive crossover.
