IFI Audio Go Blu, mini & super

Ifi Audio launches a spectacular pocket-sized amplifier and DAC that offers heavenly sound for headphones anywhere. Wired Bluetooth 5.1 (AAC, SBC, aptX, aptX HD, aptX Adaptive, aptX LL, LDAC, LHDC/HWA Codec).

We used Qualcomm’s new QCC5100 Bluetooth IC in combination with the Cirruc Logic 43131 as a DAC to create an audibly superior “Bluetooth Engine.”

All current Bluetooth high-definition audio formats are supported: aptX Adaptive and aptX HD from Qualcomm, LDAC from Sony and LHDC from HWA, aptX regular and aptX Low Latency, AAC (Apple iOS devices), and SBC (the Bluetooth codec). “simple”).

Of the 24-bit capable codecs, aptX Adaptive and aptX HD support up to 48 kHz, while LDAC and LHDC reach 96 kHz.

iFi’s “Bluetooth Engine” can also be updated wirelessly, so future codecs can be added.

The latest Cirrus Logic CS43131 is an advanced “miniature” DAC that sits at the heart of the latest range of iFi mobile devices.

Advanced 32-bit oversampled multibit modulator with mismatch shaping technology.
130dB dynamic range.
THD+n of -115dB.

This is a superior method to the traditional single-ended circuit approach. Balanced circuitry reduces noise and crosstalk. Less interference and clearer sound.

You’d typically find this setup on products at the higher end of the price spectrum, such as the Pro iCAN, but iFi are using this across their range to produce the best audio quality for all our customers.

As with many other iFi audio products, we have incorporated a custom OV series op amp. This top-notch component contributes to ultra-low noise, low distortion (0.0001%) and wide bandwidth.

An important aspect of the circuit design is its direct-coupled nature (there is no coupling capacitor), which is achieved without a conventionally applied DC servo.

DirectDrive® is equivalent to a direct signal path, which means less signal degradation. This direct signal path is unmatched in audio and is the reason the sound is so “true.”

XSpace is iFi’s analog signal enhancement circuit to get the “music” back out of your head for even more headphone enjoyment.

XBass is an analogue spatializer for headphones. It opens up the music to give the feeling of spaciousness experienced in a live concert.

TDK C0G (Ceramic Class 1) capacitors offer high stability and low losses for resonant circuit applications.

Inching closer to the theoretical ideal of pure, constant-frequency capacitance, these capacitors reduce capacitor-induced distortion to incredibly low levels.

They have a high price, but they are a perfect complement to our products.

muRata type high Q, low ESR multilayer capacitors. The “ESR control” aspect of the Muratas is something special. Its noise suppression capabilities are impressive.
