What I mean by quality is regarding their assembled products - interconnects, HDMI cables, etc... For speaker wire, I've tried many varieties and found that it makes the least difference in the system, so don't spend a ton on it.
Bare wire - just to be clear, I mean bare wire at the ends, only long enough to make the connection at the speaker or receiver. You'll be hard pressed to find speaker wire that is completely bare. That would be a guaranteed short and a dead receiver.
