iFi GO Bar Kensei: A High-End DAC/Amp with Unmatched Audio Performance

Introduction

Named after the revered Japanese title "Kensei," meaning "Sword Saint," the iFi GO Bar Kensei embodies outstanding craftsmanship and performance, tailored for audiophiles. This device is no mere audio accessory; it is designed for those who pursue incredible sound fidelity.

Pricing and Availability

The iFi GO Bar Kensei is priced at $449 and is available at various online retailers, including ifi-audio.com and Amazon. Unlike the earlier iFi Gold Bar, this model isn’t limited in availability, ensuring that enthusiasts can acquire it without fear of missing out.

Design and Build Quality

Unboxing the Kensei feels like a premium experience, presented in a meticulously crafted, eco-friendly wooden box. Included in the package are two high-quality braided cables (USB-C and USB-C to Lightning with a USB-A adapter) and a classy leather pouch. Compact and lightweight, the Kensei resembles a USB flash drive but weighs surprisingly more due to its stainless steel construction.

The device features elegantly chamfered edges and showcases a meticulously etched branding on the underside. However, the face is where the real allure lies, equipped with LED indicators for volume level, audio format, frequency, and customizable sound effects. Controls include buttons for volume adjustments and settings, along with an IEMatch switch that allows compatibility with various high-sensitivity IEMs.

While the Kensei exhibits some warmth during extended use, it’s neither excessive nor uncomfortable. However, the stainless steel body may show signs of wear and tear, such as scratches, due to its softer material.

Key Features

At the core of the GO Bar Kensei lies a 32-bit Cirrus Logic DAC chipset, capable of delivering high-resolution audio across a broad range of formats, from MP3s to DSD256 and DXD384, alongside comprehensive MQA decoding. Its construction includes high-quality capacitors meant to enhance signal clarity and minimize distortion.

The Kensei's standout features include four digital filters and two analog modes, each with specific sound characteristics. Users can switch between:

• Bit-Perfect (cyan): Ideal for transparent listening without unwanted brightness.
• Standard (red): Warmer tones, making vocal performances feel smooth.
• Minimum Phase (yellow): Emphasizes tight bass while retaining mids and vocal clarity.
• Gibbs Transient-Optimised (white): Energizes audio through upsampling, providing a more dynamic sound.

To further enhance versatility, the Kensei includes an IEMatch switch for lower sensitivity earphones, while Turbo Mode augments gain for power-hungry headphones. The output capabilities are impressive, with 477mW or 7.2V from the 4.4mm output and 300mW or 8V from the 3.5mm output.

It’s essential to note that, while it efficiently drives a range of headphones, the need for external power via USB-C can lead to noticeable battery drain on portable devices.

Sound Performance

When it comes to audio quality, the Kensei creates an ethereal soundscape that feels full-bodied yet nuanced. Testing it with different IEMs, particularly the Sennheiser IE900 connected through the 4.4mm output and using the Bit-Perfect filter, showcased its ability to reveal details previously missed in other setups. The auditory clarity offered a new depth to experiences, allowing for the appreciation of subtle musical elements.

In tracks such as "Violin Duel" from the Chevalier soundtrack, the device highlighted minute details, making each bow stroke and chord change vividly distinct. Similarly, Beyoncé’s tracks, with their intricate layers, were rendered with remarkable fidelity.

The Kensei's prowess also shines in bass reproduction, proving adept even with IEMs that aren't necessarily bass-focused. It delivered deep, robust bass sounds when enhanced with the XBass filter, bringing an intense energy to genres like electronic and hip-hop, while maintaining clarity across frequencies.

Competitive Landscape

What sets the GO Bar Kensei apart is its combination of luxurious packaging and solid performance. However, it faces competition in the portable DAC/Amp market. For instance, the Fiio Q15 offers additional features like a display and Bluetooth connectivity, making it suitable for those who prioritize wireless options. Similarly, the iBasso DC-Elite is regarded as a worthy competitor with comparable features and eye-catching design.

Conclusion: Who Should Consider the Kensei?

The iFi GO Bar Kensei is ideal for audiophiles seeking a transparent sound experience without the need for Bluetooth or parametric equalization. It excels in delivering detailed audio with its array of features, making it a valuable choice for serious sound enthusiasts. However, with its premium pricing, it might not appeal to casual listeners looking for basic functionality.

The Kensei proves to be a long-lasting companion for those willing to invest in a portable DAC/Amp that delivers performance worthy of its price tag. Its unique combination of sound quality and aesthetics makes it a compelling addition to any audiophile's toolkit.
