Aune BU2 - Headphone Amplifiers & Headphones
The Aune BU2 is a high-performance headphone amplifier and portable DAC combination, in a package of beautiful design quality. Equipped with two ES9318 DACs, a Bluetooth 5.0 chip and an R2R volume control. This set guarantees a sound reproduction with great precision and sound richness. In addition, it has a dual output, with unbalanced 3.5 mm jack and balanced 2.5 mm output. The BU2 has a very natural presentation of the music, it's very musical like previous generations but here you get more of everything.

  • Luxury headphone amplifier with built-in DAC (2x ES9318) & Bluetooth 5.0
  • Supports LDAC for lossless streaming
  • Large 4000mA battery for up to 9h battery life
  • High definition with support for 32bit/768k & DSD512
  • Support for Apple / Android / PC
  • R2R Resistor network for volume

The digital conversion in Aune BU2 is based on a duo of ESS ES9318 digital-to-analog converters mounted in parallel for accurate and clear sound reproduction. The amplification stage contains four independent headphone amplifiers. In addition, a low-ripple positive/negative power supply is used to efficiently drive all circuits.

Blue tooth 5.0
The Aune BU2 features next-generation Bluetooth 5.0, including support for aptX and aptX HD high definition codecs. This makes it easy to stream music to the BU2 from a smartphone and computer, as well as to connect the BU2 to headphones or Bluetooth earbuds.

USB-C input
The BU2 also has a USB-C input. This allows you to enjoy files in very high resolution, up to PCM 32bit 768kHz and DSD512 for an incredible quality sound reproduction.

Clock synchronization
The Aune BU2 uses two ultra-low jitter clocks, 45M and 49M, which are synchronized directly to the decoding chips via the USB interface. This ensures a natural and transparent sound.

A single control button
The Aune BU2 is intuitive and easy to use, utilizing a single knob for quick access to all parameters and controls.

R2R volume control
The BU2 uses a dynamic volume control technology consisting of an electronic switch and R2R resistors. These resistors allow the volume level to be precisely attenuated, while maintaining an excellent signal-to-noise ratio and very good dynamics.

Buy&Try applies to the entire Aune, Auralic, Quadral, Sbooster & Taga range.

Buy & try gives you as a customer the opportunity to try out the product in your own home environment, instead of standing in a stressful store and trying to form an opinion. Rooms behave very differently and affect the sound in different ways and we give you the opportunity to demo the product for a full 30 days, in your own home.

 

If for some reason you feel dissatisfied, just contact us and we will help you with the return shipping, you can also take advantage of our shipping agreements with lower prices. Costs that will be charged to the customer are the shipping to the customer and the return shipping to us at MYC HiFi. For return approval, the item must be returned in new condition and in the original packaging.

 

Regarding speakers, be aware that speakers may need a long recording time to come into their own. After a couple of hours you can usually get a taste of what to expect, but a speaker deserves 100h+ before serious listening. The speakers we sell with ribbon tweeters need several hundred hours before they start to sing. So feel free to leave the speakers on around the clock so you can quickly accumulate hours.

 

If you have any questions or concerns, do not hesitate to contact us.
