The great success of the predecessors, the HA-2SE and the Headonia – an absolute reference tube amp, inspired the Auris team to develop another, extremely powerful tube amp.
Auris Nirvana IV – from idea to reality
The Auris Audio Nirvana IV is one of those amps that performs great with every single headphone you throw at it, from the most easy to drive to the hardest – dynamic or planar magnetic. The range of supported headphone impedances is huge – from 32 to 600 Ohm. Apart from the fact that it’s maybe too powerful, there absolutely isn’t a single thing not to like about the amplifier. It looks stunning and the separate power supply gives it an extra classy look. The external PSU, which delivers the best possible constant power (no AC) to the amp section – the safest choice when trying to achieve an audiophile performance.
If you are looking for a musical instrument to deliver maximum performance or you are seeking or lusting for, a product that will make you feel as if you are in heaven, look no further than the Auris Nirvana.
Sound
Nirvana proves that bass performance from headphones can match the quality and the quantity of bass-via-massive-woofers. No loss of details, perfect clarity, precision and airiness with all the headphones plugged into it. In the matter of sound, Nirvana represents a blend of Auris Ha2 and Headonia amplifier, in the way that it takes the best of both. Balanced mode reveales many hidden layers of music and the reproduction becomes slightly more detailed.
It sounds like you’re in heaven with a dynamic, wide and very well layered sound with a good amount of warmth and tube smoothness. The Nirvana gets sound (and looks) just right and it simply is impossible not to like.
