After 3 days of heavy listening to the Signatures I will say this: If your budget is no more than $800 for a pair of speakers, I have to imagine these are the best you can get, all around ,IMHO, incredible build quality. My observations/nitpicks (and please take into account I'm not a well schooled technical audiophile) are that the low end sounds wonderful but that the tweeters struck me as too bright, at times making horns hard to listen to. Also, the mids weren't very warm which I thought left some vocals flat and disengaging. It's ironic to say, but I felt like there was too much separation with highs, mids and lows not blending together, not terribly musical. I never really found the speakers "signature' (I know) soundstage either, nothing consistent at least. I never bothered to run a proper shootout with my Vienna Acoustics' Mozarts as I felt like it wasn't practical. As a result, I've ordered Tektons' Enzo XL to run a more comparable side by side (at 3X's the $$, they need to crush to win). I am VERY curious to hear Gene's take.
btw: Rogue Audio Perseus Pre, Emotiva XPA-2 power and Pro-Ject debut carbon TT
