Initially I thought the HK was pretty good, especially if used a USB cable from my phone. I convinced myself that the Bass -6, Mid -2, and Treble +3 brought out good clean sound with some punch. Turns out it kind of does, but what this HK 19 speaker system seems to be lacking (at least to me) is a the delicate balance of all the instruments. They system just doesn't 'shimmer' like my friends Meridian system in their Jaguar. The Meridian setup singles out each instrument individually and you can distinctly hear each instrument on its own. It's just CLEAN, which I like. Not saying the Meridian is killer on bass, but it's just really clean.
Don't get me wrong, there are some recordings that sound fantastic on the HK, but generally, after hearing the Meridian system, the HK seems to be missing some key frequency responses which tend to 'muddle' or not 'bring to the front' certain frequencies. Hard to describe, but it just seems to be missing on true clarity; like someone threw a blanket over a few speakers.
I think this issue could be 75% fixed if there were a 7 band EQ, but pigs will fly before that kind of update is released.
