I was able to experience the described tonal improvements particularly well with classical music, such as Vivaldi's "The Four Seasons" (Yehudi Menuhin, His Master's Voice, 1985). Individual instruments always seemed to maintain their position as if cemented in place and subtle ramifications and nuances of individual notes seemed to be reproduced even more cleanly than I was used to. If I wanted to, I could follow them even more easily than before. The room also seemed to me to be more "stable" in all dimensions and the background seemed blacker in pauses or quieter passages, which meant that instruments and notes rich in higher frequencies in particular seemed to gain in radiance. However, all these descriptions are merely my pitiful attempt to somehow verbally convey what I experienced and they can in no way replace one’s own impressions. So, if you want to squeeze every last bit of sound out of your high-quality music system and realize its full potential, simply try out a rack like the Pagode Signature MK II model E14 from Finite Elemente presented here with your own setup. It could be worth it.
