HI Dreadhead,
In my post above, I touched on the connections issue as this was one of my primary concerns too. No need to join the amps as there is no master nor slave preamp in bridged mode. In essence, each block has its own pre with you needing to simply hook up the left outs put from your CD, DVD, AM/FM, phono, etc., to the Left Pathos and the corresponding right outs to the Right Pathos.
Regarding smooth simultaneous operation of the two units given the distance, I had thought about getting a passive preamp/linestage and decided to wait and see if the units were able to react in concert to remote commands. In my short experiece with this setup, the horizontal range of the remote is sufficient to operate both units in lock step. Take a look at Doug's setup and you'll see that he has them situated (right next to each other) which is probably how most would set them up - so this would be even less of an issue. Assuming you are using only one or two sources most of the time, it is less cumbersome than it would seem.
As this system is in my work office, I am glad it worked out as it is important to me to keep the box count down. Pictures to come soon . . .
Hope this helps.
Regards,
Garry
