I'm surprised (although I shouldn't be) that most opinions differ to mine in this regard. I took this question to mean one thing, but not influenced by an emotional factor.
If I'm fed up, happy, whatever, I know the one constant if I need to play some music is the stereo's going to be how I want it to sound. It's just been 'right', so I don't sit there and think the sound is one way or another. I don't even see how that comes into it - external factors, well, we live in a quiet area away from main roads, with Holyrood Park behind us and we live in a detached house, so in terms of setting, it's about as good as it gets.
Perhaps you're all busy looking for the next upgrade, though by the looks of things, I get the impression it might involve bio-engineering. Rather extreme chaps!
