Right now as a 568 owner I will also sit back until there is a 861.3 shipping with RC cards! Then we will know the price and see how it measures up!
With a 568, I guess it is possible to use 4 Tact RCS 2.0's with the D/A options to get what we want from the Meridian RC cards but that is retail $3600 X 4!!!
If they would make the Tact TCS unit so that it could take the digital inputs from 4 SPDIF
signals simultaneously, and then do the room
correction on all 8 channels, then do the D/A
with 24/96 or better DAC, that would be a better solution but the last time I checked the TCS couldn't be configured that way. If someone is going to the 2002 CES, maybe they could check with Tact about converting a TCS for processing 8 channels of digital input ( not 4 stereo channels of selectable digital inputs)
