No worries on more 2-channel stuff...with remotes! It's definitely in the plan. I can't say on timeline, though...
Great news! For headphone listening I don't need a remote (does anyone?), but any amp that's powering my main speakers needs to have a remote - at least for the volume control. Call me lazy, but I don't like to walk up to the amp to adjust the volume only to return to the listening chair to find out that I should have set the volume just a little bit higher or lower.
