Any Experience with Tact RCS and upsampling DAC?

Hi all. I have an SCD-1 and recently sold my Dodson DAC. My plan is (was) to either wait for one of the new players to come out, such as the Accuphase 85, or possibly get the Audiocom upgrades to the Sony. However, what about the Tact room correction units. How have they performed, especially with their upsampling DACs. I'm interested in anybody's comments or experiences.
Thanks,
David
