liquid sound

I was flipping between a tube and digital amp a while back. I visualized this in textural terms like the difference between running your hands over grass compared to polished glass. The harmonics get thrown at you a little differently. I couldn't say one was better, just different.

Minimal distortion

When I describe my system as "liquid" I mean to imply that the performance flows effortlessly between my speakers - not from them but, rather, creates a holographic presentation of the performance. Liquid, to me means no grain, no edgyness, perfect (or close to it) integration of the bass, midrange and treble. I mean to imply that my speakers have dissappeared and just the music drips into a 3d soundstage. It's a beautiful thing.
