Digital room correction, any recommendations?

Two-channel.

Lyngdorf is reported to be easy to use. But it requires A/D and then D/A conversion between preamp and amp, and I don't want to do that. I want to do the correction before conversion to the analog signal.

Acousticfrontiers, it looks like the Tact 2.2XP meets both of our criteria. Question: Do I lose any of the correction capabilities by using it between my digital source and DAC, rather than as a digital preamplifier?

Good to hear, thank you.

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'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.
