Simply...THERE IS NONE! Forget everything you knew so far about source-headphone connections. You will experience unprecedented situations. Now you are part of the musical ensemble. You are not the listener but the protagonist himself. You will hear a unique acoustic immediacy, as well as details that were simply previously carefully covered. The instruments, especially the percussion, come forward and the rhythm gains body, power, and above all a distinct position. The vocals, excellently with enough "moisture" in their timbre, will impress you, while finally in complex orchestral formations everything is simply in its right place without the phenomenon of recording compression. A small diamond, but with unique value that every serious music lover listener must possess.
