After some research, I believe I'm going to buy one of these little FiiO D3's for our bedroom system.
Since we don't watch much in the way of mainstream TV, we just cancelled our cable TV over the weekend and just have internet now. We also just upgraded our 720P 32" LCD smart TV to a nice new 32" LED computer monitor. Being a monitor, it has no audio outputs, so we need a way to get audio to my Sansui G-7000 receiver. We have a Roku Ultra in this system, and right now as a quick band aid, I'm using the Roku remote's headphone output plugged into the G-7000. It sounds quite decent surprisingly! Though doing this is ultimately running down the remote's batteries, and forcing us to use the Roku remote app on our iPad Mini 2. No biggie, but it's not optimal.
Just for fun, the rest of this system consists of a Yamaha T-1000U tuner (the tuner in the G-7000 needs some TLC), a Luxman PD-277 turntable and a pair of mint Genesis Physics II bookshelf speakers that I completely rebuilt and upgraded the crossovers in with all new high end components.
