Euterpe - Multifunctional Headphone Amplifier in Wooden EnclosureMulti-functionalAll-in-one amp can be used in many ways. Since it is multi-functional it can work like a headphone amlifier, pre-amplifier or DAC. Euterpe can work with its own integrated DAC, or you can connect it with another DAC. Also, its pre-out function can be used in case you want to connect it to a smaller system at your home.A Headphone StandThe possibillity to be used like a headphone stand , makes Euterpe strangely utilitarian for such a high-end piece of hardware. Your headphones fit right on top, with a shallow saddle cut into the wood, to keep the cans in place. It can take a full-size headphone and won't heat up or burn your precious cans.Internal DACDAC inside can play modern sources. OTG input capability has some baseline specifics, including a decoding capability of up to DSD128, PCM max 32bit/384kHz. An XMOS USB DAC and ESS Sabre chipset represent the brain of Euterpe. The DAC quality is impressive, with beautiful details captured.AmplifierEuterpe is a single-ended headphone amplifier with unbalanced circuit design, so there are no balanced inputs or outputs. The lineup of tubes is classic Auris, with the use of two 7-pin Ei PL95 tubes, which are the equivalent to 6DL5, and a single ECC81 input tube, also known like 12AT7 (running in Ultra-Linear mode). The output power is just a shade lower at 0.9W into a 32 Ohm load. The magic of Euterpe is really when it is connected to a high-end DAC which tells you a lot about how good that amp can be inside that beautifully crafted wooden enclosure.Impendance SelectorTo make your headphones shine in the best possible way, we make sure Euterpe has impedance swich marked with L/H (low/high) The inference here is a wider range and simpler switching design at 32-80 Ohm and anything greater than 150 Ohm. With the majority of planar headphones, they tend to rate less than 80 Ohm and are more impedance agnostic than dynamic headphones. You need to have that switch set to low or L.Linear PSUEuterpe power supply is an external regulated linear power supply, with a switchable 115/230 VAC capable output, and will keep noise to the minimum. It uses a fairly stiff but sturdy 4-pin connector 1m cable, so you can place the two units pretty far apart.TechnologyThe Euterpe comes with the technology one would expect from a Auris Audio amplifier: It is composed of a xmos chip that handles USP input duties, a Sabre ES9018 chip handles the conversion duties, a 12AT7 tube handles pre-amp functions, with a Mundorf capacitor in line between the preamp and power tubes The supplied power tubes are NOS (new old stock), branded Ei and stamped Yugoslavia: A single ECC81, dual-triode tube serves as the Euterpe's input stage, while a separate PL95 pentode power tube is provided for each channel; these feed the output transformers. A selector set allows you to use the PL95s, as EL95s with a lower voltage The power supply has a captive five-pin cable that connects to the amp, and a 15-amp IEC connector for a standard grounded AC power cord.UseEuterpe allows you to use digital sources such as PC, or mobile device. For such an exotic piece of gear, the Euterpe is "a piece of cake" to use. There's a master power switch on the power supply, but the main switch is built into the volume control. Just turn it fully counterclockwise to turn the power off. It's as plug 'n' play as a tube headphone amp gets.Design

Nirvana - Desktop Headphone AmplifierFrom idea to realityGreat success of the predecessors, the HA-2 and the Headonia - a TOTAL reference tube amp, inspired Auris team to develop another tube amp, which is going to be extremely powerful.The Auris Audio Nirvana is one of those amps that performs great with every single headphones you throw at it, from the most easy driving - dynamic to the hardest, planar magnetic, and the other way round. The range of supported headphone impendances is huge - from 32 to 600 Ohm. Apart from the fact that it's maybe too powerful, there absolutely isn't a single thing you don't 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.SoundNirvana 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.TechnologyIn technological terms, Nirvana qualities are reflected in: Carefully selected and pre-tested tubes - should last for 10.000 hours. It is powered by iconic EL34 by Electro Harmonix, a most common pentode found in British amplifiers. The drive tube is ECC82 by Tung- Sol, popular in audio world as low-noise tube for most popular amplifiers circuits. Transformers - manually wound on double C core and manufactured in-house in compliance with strictly defined requirements. High quality components - branded Mundorf, Rubicon, Wima etc...DesignNirvana features a classic retro design with wooden plates on top and at the bottom, with black leather finishing in between.It is a two-piece stylish design with external PSU, attached to the main amplifier via high quality 1m long umbilical cord. Two transformers on the top of the amp are noticeable with a glass protection for tubes Tubes are inserted into easily-accessible sockets on the top Two backlit VU meters and two headphone outputs ( 4-pin XLR + 6,3mm stereo ) Three dials/selectors on the top panel, for output impedance, volume and inputs Two pairs of RCA inputs with a pair of 3-pin XLR and a power input on the back panel PSU is made of aluminium chassis with a cord wrapped with a proper strain relief Supported input voltage selector 110V/220 V
