“Pros: Tonally similar to its predecessor yet packs in that last ounce of oomph, slam, musicality and finesse in just the right spectrums of audio. Worth it!”
“Went into the shop to audition the original Micro (my current desktop setup) vs the BL…….I have concluded that the upgraded components really make that last ounce of difference in an already fine product! Bass slam that was already pretty good in the original, is now more pronounced and adds to the oomph and color and the low end. Overall clarity, already good on the original, is now slightly increased and subtly smoother and sweeter. Overall image width and height, on the Senn HD599, is about the same to me, but then, with the added clarity+sweetness+slam, that same stereo image suddenly snaps into sharper focus on good recordings. On bad or average recordings the BL actually makes the music tolerable due to the added musicality. Ahhhh… musicality… that is the one elusive trait which could justify giving up my beloved Micro. The BL definitely has a palpable increase in musicality which I didn’t even know I was hungering for, til today. ”
Thank you Hardlok!
