(the Nirvana) gives a more 3D like impression to instruments and vocalists with a good recording, almost a sculpted effect, especially with smaller sized chamber and Jazz music.

(The Lazuli Nirvana) deliver(s) what you are seeking; that last measure of transparency, air, and clarity that we all chase, but seldom find.

Eric Neff, Headphone Guru, March 2019

The Lazuli Nirvana provides a deep-rooted sense of musical immersion and envelopment. From a technical view, these qualities reminded me of an upgrade in amplification – more depth, better separation, more grip, and appreciable harmonic structure.
