Beyerdynamic A 20 Headphone AmplifierRegular price $799.00 Sale price $779.00 Save $20.00
The A 20 headphone amplifier is used to operate up to two headphones with a nominal impedance from 30 to 600 ohms.
The power amplifier, of a discrete design, and the combination of selected high-grade components inside the device allows even high-impedance hi-fi headphones to be driven flawlessly over the entire frequency range. The A 20 supplies an impressively natural and transparent sound with excellent resolution and spatiality. The volume control adjusts the volume for both headphone outputs, which are connected in parallel. Its handy button is made of solid aluminium and hides a high-grade ALPS potentiometer with smooth volume values.
Gold-plated RCA phono sockets on the rear are used to connect the audio source and allow a signal transmission without loss. The input is looped-through, which means audio signals that are present at the INPUT sockets are routed to the OUTPUT sockets, even when the device is switched off. Due to the hard-wired design there is no loss.
The high-quality metal housing is made of brushed aluminium and protects against signal scattering and vibration.
Due to the internal wide-range power supply the A 20 can be operated with 110 V/60 Hz and 240 V/50 Hz, allowing for global use.
Audiolab M-DAC mini Portable DAC & Headphone AmplifierRegular price $899.00 Sale price $799.00 Save $100.00
The fourth model in the M-DAC range: The M-DAC mini. As the name suggests, the M-DAC Mini is the smallest hi-res DAC/headphone amp in the range.
The M-DAC Mini’s design deliberately blurs the lines between home hi-fi DACs and pocket-size portable units. It is ideally sized to sit discretely on a desk or table, with accessible, easy-to-use controls and a traditional analogue volume knob.
There is also sufficient internal space to enable in the inclusion of discreet audiophile-grade components in key circuits, eschewing the space-saving compromise often inherent in portable DAC designs. Yet its diminutive form factor makes the M-DAC Mini easy to carry and place wherever it is needed, untethered to the mains supply thanks to its rechargeable battery.
Like the M-DAC+, the M-DAC Mini is equipped to process PCM audio data up to 32-bit/384kHz via USB, ensuring it is primed to take full advantage of hi-res digital sound both now and in the future. The USB input also supports DSD64, DSD128 and DSD256 – a significant inclusion, as DSD has an important role to play in the developing hi-res audio scene.

Beyerdynamic A 2 Headphone AmplifierRegular price $2,299.00 Sale price $2,279.00 Save $20.00
The A 2 headphone amplifier is used to operate a maximum of two headphones. As the two headphone outputs are connected in parallel, the connected headphones should have the same nominal impedance between 16 and 600 ohms.
The functions of the A 2 can be selected on the device itself or via the supplied infrared remote control. Furthermore, the headphone can temporarily be muted via the remote control.
The components inside the device are illuminated in a warm orange glow and can be seen through a transparent cover, which is made of a special ceramic printed glass with wave-shaped windows. The special circuit design features an amazingly natural and brilliant sound reproduction with an excellent resolution and spatiality. Discrete components are exclusively used as audio components. They may be bigger and require more room, but they work more precisely and reliably.
The volume control is made of solid aluminium with a high-grade motor-controlled ALPS potentiometer inside, which allows setting the volume via remote control. The selectable output impedance ensures an ideal control range of the volume potentiometer for all headphones no matter if they have a low or high impedance. With the selectable gain the A 2 can optimally be adjusted to the connected audio source.
Due to a microprocessor-controlled intelligent relay, unpleasant cracking noise is avoided when turning the A 2 on-off or when changing the audio source.
The gold-plated RCA connections on the rear allow the connection of audio sources and provide a signal transmission without loss. One input is passively connected with the line output of the A 2 to loop through incoming signals even when the A 2 is in standby mode. In this case the A 2 has only to be powered up if you want to listen to your music using your headphones. Two buttons to select the signal source are backlit in orange to indicate which signal input is currently active.
The supplied headphone stand can be mounted to the bottom of the A 2 for storing the headphone.
The selectable supply voltage of 110 - 120 V or 220 - 240 V allows the device to be used worldwide.
• RC 2 infrared remote control
• Headphone stand including mounting set
• Power cable (type depending on the version)
