The Adcom should work fine -- it's rated at 100W, I believe, much like Outlaw's 7100. Being only two channel, however, it'll of course only be good for a piece of the home theater. The Nakamichi does include a 5.1 analog input, and a number of people have elected to use such receivers as temporary amps while saving up for the real thing (there's a lengthy discussion of it here -- D.Rowe and Qyv10 are both using a receiver as a power amp while they save up for a power amp). This arrangement will not sound as good as a real amp -- the receiver has lower power output to begin with, plus an extra volume control in the signal path, plus less headroom and reserve than a dedicated amp will have. The upgrade from a Pro-Logic receiver's front-end to a 950 should certainly provide quite a lot of enjoyment even under these circumstances, however, and the Adcom and Nakamichi could be used to run your five home theater speakers and have the second zone (connected to the Adcom, most likely, although you could use two channels from the Nakamichi for this and run your mains with the Adcom for the time being) feeding the Niles switcher and on to the three pairs of remote speakers.
