Auris Audio
Nirvana
The Nirvana is Auris Audio's full-sized, single-ended Class-A tube headphone amplifier, built around iconic EL34 power tubes paired with an ECC82 driver tube and fed by a dedicated external power supply for constant DC power delivery ([HeadAmp official listing](https://www.headamp.com/products/auris-nirvana), [Headfonia review](https://www.aurisaudio.shop/blogs/reviews/nirvana-review-by-headfonia)). It is rated at 6.5W of pure Class-A power per channel, features backlit VU meters and a selectable output-impedance system spanning 32 to 600 Ohms to match a wide range of dynamic and planar magnetic headphones, and has since been updated through several generations (Nirvana IV, Nirvana 6) ([HeadAmp official listing](https://www.headamp.com/products/auris-nirvana), [Bloom Audio Nirvana 6 listing](https://www.aurisaudio.shop/products/nirvana-6)).
