Every IEM I have tried it on is greatly improved. Broke it in on my Monarchs and they sounded like a TOTL IEM. Great articulate bass, rich mids and airy treble. I have never heard better. Serious IEM listeners should keep this cable in their collection.
Very dynamic sounding cable, super black background and wide soundstage presence. Pairs well with multiple IEMs, expensive but it is a truly magical cable
