First off--Frank and his team are first rate people. Buying his products for the outstanding service alone is a smart idea. Let alone the fact that the products are first rate as well...
My OmegaStar 440 (high current) was recently upgraded to the Insight+. And I haven't had the time to really do any critical listening...but hope to later this week(end).
Initial Impressions? Hubba Hubba. A stark improvement, I'd say. And it's tough for me to easily define. I expected for added clarity (or veil removal)... And that was clearly evident. But what I did NOT expect was that the veil seemed to be removed both in the foreground and in te background. The foreground, I expected... The background, I did not. It's hard to describe, but it was like there was nothing (behind) the music. So my first reaction was that of puzzlement, and to turn up the volume. But I immediately realized that this (volume change) had nothing to do with it at all. The music was just....clearer. Cleaner. More distinct, and with nothing in the background...
So now...I gotta upgrade the pre-amp!
Well done Frank!
