Deluxe USB DAC The world's most powerful headphone amplifier in its size器。


Go, Go, Go!

The GO bar is our top-of-the-line ultra-portable USB DAC/headphone amplifier。

Whether you're commuting to remote work, working at your desk or just traveling for fun, the GO bar is the perfect portable way to make headphones sound like heaven攜方式。

Connect to your laptop, MacBook, tablet or smartphone or any other device with a USB port Enjoy stunning sound quality at home, office or on the go撼的音質。

Accessories include a leather travel bag and a Lightening to USB-C no need to buy a camera connection kit plus a USB-C OTG cable and a USB-C to USB-A adapter配器。

Small but complete全

The DAC section of the GO bar uses a powerful 16-core XMOS microcontroller to process the audio data received on the USB input。

The iFi team programmed the XMOS firmware to optimize sound quality and ensure perfect cooperation with the GO bar's 32 bits Cirrus Logic DAC chipset作。

Custom filters minimize pre-echo and ringing artifacts Our GMT precision clock system ensures ultra-low jitter動。

  • Ultra-res PCM up to 32-bit/384kHz via USB
  • Native playback up to DSD256
  • 2x DXD
  • MQA full solution

GO bar is perfect for your needs

Four custom filtering options:

  • Bit Perfect No digital filtering, no pre- and post-ringing振鈴
  • Standard Moderate filtering Moderate front and rear ringing振鈴
  • Minimum phase slow roll-off Minimal front and rear ringing後振鈴
  • Gibbs Transient Optimized minimal filtering with no pre-ringing and minimal post-ringing振鈴

Two analog processing modes:

  • XBass+ An analog bass boost that adds back lost bass response for a more accurate reproduction of the original sound地再現原聲
  • XSpace– A holographic soundstage opens up your music to give you the spaciousness of a live concert空間

Shell Design

The GO bar's smart alloy housing features buttons for precise volume adjustment and controls for various sonic tuning options。

Colored LEDs provide a guide to the format and sample rate of the digital audio currently playing and whether XBass+ and/or XSpace are being usede。

One end is a USB-C input and the other end is a pair of headphone outputs出。

  • 4.4mm fully balanced output Headphones with balanced cables/connectors can benefit from the GO bar's fully balanced circuitry電路
  • 3.5mm S-Balanced output Our S-Balanced technology reduces crosstalk and noise by 50% over conventional single-ended headphones0%

the power of balance

Despite its small size, the analog circuitry of the GO bar is a balanced circuit design with a symmetrical two-channel output stage出級。

This reduces noise and crosstalk in the signal path by completely separating the left and right channels. This is often found in larger and more expensive amplifiers中。

The circuit is filled with high-quality discrete components and special attention has been paid to power supply filtering to significantly reduce signal noise introduced through the USB input噪聲。

Purity and Strength

Amplifier design combines sonic purity and power。

  • 475mW into 32 ohms​
  • 7.5V into 600 ohms

A headphone amplifier this small can't match the GO bar's ability to drive tricky headphone loads or work with a wider range of headphones。

The GO bar also integrates two power adjustment technologies:

  • iEMatch attenuates power to accommodate high-sensitivity headphones and IEMs to remove background noise and increase usable volume range範圍
  • Turbo boosts gain by 6dB for more power-hungry headphones耳機

*Please note that the GO bar may not work on iPhone 6S and below when the phone battery is low (<30%)ne。

Birthdays must be glittering!

To celebrate iFi's 10th anniversary we designed a striking special edition GO barr。

Limited to 1000 units The 10th Anniversary Limited Edition GO bar features dazzling gold-plated trim and a copper chassis for enhanced build quality and shielding performance屏蔽性能

  • Enhanced power supply filtering
  • Weight 64g 40g heavier than standard versiong

GO bar 10th Anniversary Limited Edition is the golden ratio among true ultraportable USB DAC/headphone amplifiers例”。

XMOS 16-core chip processes audio data received via USB digital input

 

This new low-latency XMOS microcontroller greatly enhances processing power. Compared to current generation octa-core chips, this new 16-core IC offers twice the clock speed (2000MIPS) and four times the memory (512KB) as well as the latest SuperSpeed USB standard 標準。

iFi's in-house digital development team programmed the XMOS firmware to optimize sound quality and ensure perfect cooperation with the 32 bits Cirrus Logic DAC chipset used in the GO bar作。

Hi-Res True Native supports all music formats from MP3 to DSD256PCM384 and DXD384格式
MQA is an award-winning UK technology that delivers the sound quality of pristine recordings。

 

GO bar uses MQA technology to receive and decode MQA audio for master sound performance現。

Extensive jitter removal technologies for the digital arena including our GMT global master time femtosecond precision clock and smart memory buffers衝器。

 

This represents a completely out-of-the-box system digital solution to solve the jitter problem once and for all動問題。

This is an approach over traditional single-ended circuits Balanced circuits reduce noise and crosstalk。

 

Clearer sound with fewer distractions。

You would normally find this setup in the higher price range like the Pro iCAN Signature but iFi is now using this setup across its entire range to deliver the highest quality audio to all of our customers的音頻。

TDK C0G ceramic capacitors provide high stability and low losses for resonant circuit applications耗。

 

These capacitors are getting closer and closer to the theoretical ideal of pure frequency constant capacitance, reducing capacitor-induced distortion to a level that is virtually non-existent平。

They are expensive but the icing on the cake for our products花。

muRata Controlled Low ESR High Q Multilayer Capacitors。

 

Murata is special in terms of ESR control Their noise suppression is impressive象深刻。

Panasonic OS-CON capacitors total 5,410uF with extremely low equivalent series resistance (ESR) excellent noise reduction and frequency response characteristics性。

 

In addition, OS-CONs have a long life due to the solid electrolyte with little change in ESR even at low temperature也很小。

They are not common in products priced under $1000。

Tantalum capacitors are another example of our preferred top-of-the-line components

 

These polarized electrolytic capacitors have excellent frequency and stability characteristics with ultra-high volumetric efficiency率。
