Yeah Michael_A. Let me tell you. I'm all over the place with this thing. I just did another test of small vs. large last night. Switched to small..calibrated everything. It still lacked in the fullness of sound. My "sound" conclusion on this is that when switched to small the 630 actually does a compression of the audio, or a filtering. Either way, unless I really did have "small" speakers I don't want it. I did everything...set the crossover to 200 even. That helped a little, but it still lacked, and it gave the sub too much to work with on bigger scenes. Nope. I have to believe that Large is the only way to go with our speakers and this receiver.
I've contacted Harman Kardon twice and I got two different answers when I brought this up. My question has now been forwarded to an engineer. When I hear back from him/her I'll post up the results of that. I'm sure, as there are a few owners of H/K receivers here, more people would like to know what's really going on.
Or maybe mines a lemon. Who knows?! We'll see I guess.
