Recently updated the Mac OS to High Sierra and noticed a low frequency improvement.
After uninstalling the previous Amarra library, I installed 4.1, then rebooted the OS.
Because I have a large library, I let it acquire the metadata overnight and in the morning quit Amarra, to finalize the library.
After work I had time to audition and sampled a few tracks then, optimized with • IRC (1.2.4) • Interfaced with an Opera Browser (major sonic improvement) • Selected Exclusive mode. To finalize these settings, I rebooted after each. (computers love this) The result is nothing short of stunning. ¯\_(ツ)_/¯ ॐ
