Auris Audio Euterpe Multifunctional Headphone Amplifier is an all-in-one amp that encompasses three key functions: a pure tube Headphone Amplifier, Pre-amp and a DAC.
Multi-functional
All-in-one amp can be used in many ways. Since it is multi-functional it can work like a headphone amplifier, 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 Stand
The possibility 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 full-size headphones and won’t heat up or burn your precious cans.
Internal DAC
DAC 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.
Amplifier
Euterpe is a single-ended headphone amplifier with an 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 as 12AT7 (running in Ultra-Linear mode). The output power is just a shade lower at 0.9W into a 32Ω 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.
Impedance Selector
To make your headphones shine in the best possible way, we make sure Euterpe has an impedance switch 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 PSU
Euterpe 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.
