Hi Sean - it's still settling in, however immediately there are definitely some noticeable differences from my current system. The KWI-200 is very well balanced, perhaps a tick to the slightly warm side of things. Excellent dynamics and frequency extension. Very solid image placement across the soundstage, with a nice foundation in the bass. Definitely more solid state sounding vs. the LS100, as you would expect. The DAC module is fantastic, albeit more bright than my MW Oppo 105. Still haven't tested out the phono module yet. It's a brand new unit and I've noticed the sound go from darker to brighter over the course of the day. More break in and listening to come tomorrow!
I will say that in many ways it's the best sound I've heard from my system and speakers. If I were starting over from scratch, there is no doubt that the KWI-200 would deserve serious consideration to be at the heart of my system as it is an incredible value, especially as a one box solution with the optional modules. Simple, easy to use, and sounds terrific!
