Using with a Sony MDR-Z1R with 4.4mm balanced termination. Much clearer separation, more 3D soundstage. Slight reduction in sibilance and bass quantity but improved bass focus.
This is the best cable that I have own so far. While it is the most expansive cable (I go for those good but reasonably priced cable - but only by a small margin from the next most $$ cable), it beats the rest of the cable by huge margin in term of performance - huge sound stage, fantastic instrumental separation, good bass, energetic male and female vocal but not bright.. Strongly recommended.
