Limited to 1000 pieces, the 10th Anniversary Limited Edition GO bar is smothered in show stopping gold-plate and boasts:Ī copper chassis for enhanced build quality and shielding plus an enhanced power supply filtering.
IFi are celebrating their 10th anniversary and they have created a special edition of the GO bar.
A column of coloured LEDs provides a handy guide to the format and sample rate of the digital audio currently playing, and whether XBass+ and/or XSpace are engaged. The GO bar’s smart alloy case sports physical buttons for precise volume adjustment plus controls to select between various sonic tuning options. They can be engaged separately and together. XSpace, a holographic sound field to open up your music to give you the spaciousness of a live concert. XBass+, which is an analogue bass boost to ‘add back’ lost bass response for more accurate reproduction of the original and The iFi Go bar has implemented two analogue processing modes: You can switch between regular and turbo modes by simultaneously pressing the volume up and down buttons. Turbo – ramps up the gain by 6dB to satisfy more power-hungry headphones. IEMatch is available for both balanced and single ended outputs and you can enable it by the means of a tiny switch located at one side of the unit. IEMatch – attenuates power to suit high-sensitivity headphones and IEMs, it removes background noise and increases usable volume range. The iFi GO bar also incorporates two power tuning technologies: In simple words this means that it is going to deplete the battery of the host device faster than you might think. The amp is capable of 475mWPC into 32 ohms or 7.5V into 600 ohms from the balanced output making the iFi Go bar one of the most powerful USB dongles in the market.Īlas, such high power output comes at cost, the power consumption of the Go bar is as high as 4W or 800mA when the FiiO KA3 is just 120mA.

The circuitry is packed full of high quality components and special attention has been paid to power supply filtering too, dramatically reducing signal noise introduced through the USB input. This is something usually found in larger and more expensive amplifiers. This reduces noise and crosstalk in the signal path by fully separating the left and right channels. Then there is a discrete analogue circuitry that sports a balanced circuit design with a symmetrical twin-channel output stage. Gibbs Transient Optimised – minimum filtering, no pre-ringing and minimum post ringing.
Minimum Phase – slow roll-off, minimum pre and post ringing Standard – modest filtering, modest pre and posting ringing The DAC section of the iFi GO bar uses a powerful 16-core XMOS microcontroller to process the audio data received at the asynchronous USB input.Ī 32-bit Cirrus Logic DAC chipset is used for D/A conversion supporting resolution up to 32-bit/384kHz PCM, native DSD256 and full MQA decoding.Ī customised digital filter minimises pre-echo and ringing artefacts and a Global Master Timing precision clock system ensures ultra-low jitter.įour digital filtering options are available:īit Perfect – no digital filtering, no pre or post ringing The detailed technical specifications are available here.
#Ifi go bar review portable
The iFi Go bar is an ultra portable USB DAC/headphone amp that connects to your laptop, MacBook, tablet or smartphone or any other digital device with a USB port.Īt one end is an asynchronous USB-C input and at the other a pair of headphone outputs.Ī 4.4mm fully balanced output – headphones with a balanced cable/connector can benefit from the fully balanced circuitry of the GO bar and 3.5mm with S-Balanced tech output which cuts crosstalk and noise by 50% with regular single-ended headphones. IFi is a little late to the party but as they say better late than never. USB DAC/amp dongles are becoming the new trend and not without a reason since they are portable, don’t require charging and their sound performance is rapidly improving. You can buy them from all authorized dealers around the world. The price of the regular Go bar is $329 and that of the limited anniversary edition is $499. The review samples were kindly loaned to me for reviewing and I didn’t receive monetary or any other kind of compensation. Pros: + Natural timbre and very musical sounding
