Two items:
1. A mini-HDMI cable that is small enough to get through STANDARD 3/4" conduit. All the current HDMI cables have ends on them that are simply to big to get through standard conduit. Even it is a cable that has no 'shell' on one end of the HDMI cable that can be snapped on once the cable has been run, that would be awesome. Because the HDMI head will fit through 3/4" but once the 'shell' is on the end of the cable it won't fit.
2. A headphone amplifier that plugs in and runs by a remote control. I have good headphones, but my receiver is in my basement. When I plug in my headphones the speakers in the room turn off, and there is no way around that. So, I want to use the 'line out' from the receiver. Yet, I can't use that with my headphones unless I get an external headphone amplifier. But, most external headphone amps not only cost a good deal of money, but they run on batteries! Plus, you gotta control the volume on them manually. Not cool at all. I'm about to buy a stereo receiver just so I can run my headphones. That just seems ridiculous.
