Just got them set up, they look very nice to me. I have them set up on Audioengine's A2 speakers stands which look hilarious but it works. They are long, with a small front as expected--looks like someone put the speakers on the wrong side for those used to a more traditional layout. I have the dark oak finish, and with its satin sheen, looks very good. It's a very subdued look and doesn't draw much attention to itself.
I have them hooked up to the small Audioengine N22 amp, with a Behringer UCA202 off my computer.
First impression is that they work very good off-axis. There's not very much lobing as I move my head around, and I would happily call it a near-field capable speaker. They still sound better further back, but work similarly as well as many near-field monitors in close range. I did have to toe them in quite a lot to optimise the sound.
In respects, they are easier to set up a stable sound stage than my Audioengine A5's, which sound noticeably less stable at the same close ranges, and do not image quite as well.
However, the S30's are not a neutral sounding speaker. There appears to be some noticeable boost to the treble and bass. It could be some anomalies in my particular setup, but it is what I hear. The Audioengine A5's sound more natural and flat in the same space, and I prefer that. It's not entirely bad--the S30's definitely sound more lively, it's just that it doesn't feel quite right. The mid-range seems a bit recessed.
In terms of clarity, the S30's are particularly good in the mid-range. Noticeably clearer than the A5's. Treble is a bit soft, yet sounds a bit overemphasized. Seems to be some distortion there as well, as if the tweeter is playing a bit more than it should. Bass is quite prodigious for such a small speaker, and unfortunately it feels like a noticeably weak link. It's not particularly well sorted, a bit too emphasized, thick, indistinct, and all around not particularly good. It's certainly there though (in spades), and better than none. The A5 has similar bass reproduction in many respects, perhaps with a slight edge in clarity and neutrality.
Overall, the speakers present a good and enjoyable sound, but it does not have the ability to approach realism the way my Sierra-1 NrT's can reach for (but not quite grasp). There's just too many missing elements for it to.
But that it's $219 is the real point. I don't think I've heard, or seen anything that can do quite as well as a 2.0 setup at that price. I might be critical of it in the absolute sense, but within the price bracket... I really have to give it nothing more than a top rating.
