S1nn3r: within the 5 weeks since last post I hear better coherence and further improvement in smoothness. My problem now is that I have a harder time remembering the SE version as the time go by and my hearing get adjusted to the GR.
For me there are two ways of evaluating hifi: firstly, I approach what I hear with my intellect and analytic competence. Secondly, and this is much more important, I try to detect how I listen to music over time; can I relax, do I listen with a lot of volume, do the music engage me emotionally etc. I can say that nothing I loved with Kensington SE is gone. It is as if the fine qualities of SE have just been further refined in the GR version.
