All speakers are fussy about positioning to get the best sound out of them. Of course, some are more than others. The Quads are indeed not as demanding as the Evo 4.2s which require a bit more care, including on the height of the tweeter and mid driver relative to the ear.Are the Evo 4.2s fussy about positioning? I think the Quad S2s are really not as they have a small port.
I would imagine a one box solution over separates.
When was the last time you remember someone employing separates not fretting over cables, even those for carrying digital signals at that?
