For me I though there was an obvious and distinct difference between the big Noesis and little for music. The highs were sweeter and smoother, the overall sound was way more addictive, I wanted to turn it up more, soundstage was bigger etc. On my song clips it was so clear to me which I preferred, well on the other guys clips too. With the big Noesis I didn't want each clip to end it sounded so sweet, with the little Noesis it still sounded damn good but didn't draw me in as much. Some songs had a little bit of a harsh edge with the little Noesis that wasn't there with the big guys.
BUT!!!!
I REALLY liked the little Noesis. It is the 2nd best speaker I've heard in my room, I thought it was easily better than my old eD Cinema 12's and I liked it better than the 888's and the DIY SEOS Tempest. When I heard the 888's I had no thoughts whatsoever of wanting to buy them. With these little Noesis I would have been curious and may have pulled the trigger. Of course with the big boys I knew immediately I was in trouble and had to find a way to make it happen even though it was an obscene amount of money.
I love the big Noesis so much because of my preference for music. I listen to music all the time, I always have been that way and I know I always will. For me the big Noesis is a no-brainer because I get an incredible movie speaker that has the sweetest music sound I've ever heard. If however, I just watched movies I would buy the little Noesis instead, unless I had a bigger room.
Now, of the movie clips we watched the only one where I really noticed a difference was the Iron Man 2 ACDC song, and come to think of it none of the other clips had music playing. Still, and I don't know why this is, but my preference towards the big Noesis is much greater when hearing just the actual song (no movie) than when I heard Shoot to Thrill (from Iron Man) in an actual movie. Weird, but that's how it works for me.





Before the big Noesis came along I thought I was more of a sub guy than speaker guy. Hearing it for the first time changed all that, even though I had heard quite a few different speakers by then. Would the same have happened if I heard these smaller Noesis without hearing the big ones? I'm not sure, be they would have come closer than anything else I've heard.
