iFi GO blu Review: A Versatile DAC/Amp for Audiophiles

Sep 25, 2024 387 views

The iFi GO blu stands out in a crowded market of portable DAC/amps with its sleek design, comprehensive feature set, and the promise of a rich audio experience. iFi Audio, known for its stellar audio products, has managed to put together a compact device that not only looks good but also feels great in hand. This DAC/amp isn't just a pretty face; it's designed to evolve with user needs through over-the-air updates for new Bluetooth codecs.

Pricing and Availability

The GO blu retails for around $200, accessible via ifi-audio.com and major retailers like Amazon. For enhanced usability, consider adding the GO blu case for an additional $29. This case allows convenient clipping to clothing, positioning the device closer to the mouth during calls.

Build Quality and Design

In terms of size, this device is remarkably compact, reminiscent of a 9V battery. Wrapped in a soft-touch polymer, the GO blu features copper accents that lend it a premium feel. A unique aspect of its design is the infinite scrolling ChronoDial on the right side, providing precise volume control along with multifunctional capabilities for playback and call management.

The top of the device displays an LED indicator for EQ presets, Bluetooth connection status, and digital filter mode. Audiophiles will appreciate the inclusion of both balanced 4.4mm and S-Balanced 3.5mm outputs, while the bottom hosts a USB-C port that accommodates both charging and high-quality audio up to 24bit/96kHz.

Feature Highlights

Now let’s dive deeper into the standout features. The GO blu includes three EQ presets: XBass, XSpace, and the combination of both. While the XBass mode adds depth to the low-end frequencies, XSpace enhances soundstage. Although more precise bass control would be a boon for serious bass enthusiasts, the presets still contribute to an engaging listening experience without overshadowing other elements of the mix.

Unlike typical single-ended circuits found in devices at this price point, the GO blu employs balanced outputs, significantly reducing noise for clearer audio. The inclusion of Qualcomm's QCC5100 chip, paired with Cirrus Logic 43131, supports a range of codecs including aptX Adaptive, LDAC, and AAC, while allowing for future updates.

Taking calls through this device is facilitated by the active noise-canceling features powered by its built-in microphones, making it suitable for commutes or workplace environments. The GO blu can easily tackle a full workday with its ten-hour battery life, and impressively, it can be fully recharged in just 40 minutes with a high-power charger.

Audio Performance

When it comes to sound quality, the GO blu delivers an elevated auditory experience. Whether connected through its 3.5mm or 4.4mm ports or using wired USB-C, its output is rich and dynamic. I tested it with various in-ear monitors (IEMs) from brands like 1MORE and Sennheiser, and was thrilled with the performance across genres.

I specifically wanted to gauge the difference between lossless codecs, using the GO blu with a Pixel 7 Pro and LDAC. The results were beautiful, showcasing an expansive dynamic range; even with the iPhone—limited to AAC—the sound quality remained impressive.

The wired connection opens up a world of possibilities, especially with high-res audio sources. I experienced moments of pure musical clarity with tracks from Paul Simon and Michael Abels, where the soundstage felt extraordinarily vast. It’s this level of detail that truly captivates, granting listeners the opportunity to explore the intricate layers of their favorite compositions.

Competitive Landscape

In the competitive arena, the iFi GO blu faces rivals like the Zen DAC 3, which serves more of a desktop purpose with additional features. The FiiO BTR7 also makes a strong competitor, offering many similar functionalities but lacks built-in mics for calls and falls short in battery duration. The Qudelix 5k too is a noteworthy alternative, priced lower and packed with an engaging companion app offering granular EQ control, although its soundstage doesn't quite rival the GO blu.
