I have the A5+ speakers connected to my iPod via an Apple 30-pin to RCA cable that allow a USB connection for charging. The A5+ speakers have one RCA and one mini plug connections along with a USB port for charging. The difference between Apple lossless on the iPod and a direct connect to my SACD player is significant, but the iPod sounds great for anything but critical listening and if I'm going to do that I have my main system in the next room.
I had the A2 speakers in the same room and they are not quite enough for a larger space. They were able to fill the room with a nice background volume, but in comparison the A5+ speakers are significantly better. My wife's reaction to the A5+ speakers was that they were not as big as she expected and I had even built a mock-up to set on the shelf.
For a living room you really need the A5+.
