Free Lifetime Technical Assistance
SKU: V90-BLU5 HD Silver



The V90-BLU5 HD is a High-Definition Bluetooth Receiver
and flexible Input Extender.

  • High-Tech Bluetooth Streamer with special DAC and SRC Design
    for complete High-End Bluetooth Playback
  • Bluetooth 5.0: more available bandwidth and transmission
  • AptX HD for wireless High-Resolution Bluetooth transmission
  • Separate High-End DAC and SRC Circuit Design with
    Re-Clocking and Up-Sampling
  • Input Extender with Flexible Input and Output Options
  • Easy to integrate in any existing HiFi Setup

The V90-BLU5 HD is a sophisticated Bluetooth receiver ideal
for streaming Hi-Res music formats from smartphones, tablets, MACs and PCs
right to your favorite HiFi system. It comes with an improved Bluetooth 5.0
standard for increased range and transmission bandwidth and aptX HD support.
Compared to the majority of Bluetooth receivers that use the integrated DAC on
the Bluetooth chip itself, the V90-BLU5 HD goes the true high-end way. It is
using a separate DAC with re-clocking and up-sampling, based on the first-class
Burr-Brown chip PCM1781D. Bluetooth has never sounded this good, and you will
finally have the proper integration for high-end systems, where Bluetooth is
used for serious listening. Retain all the warmth, detail, transparency and
dynamics in your music, which is unfortunately so often missing in other
Bluetooth implementations.

Burr-Brown PCM 1781D 24/192 Internal DAC

The big majority of Bluetooth receivers are using
digital-to-analogue converters which are directly built-in on the Bluetooth chip.
These are mostly of mediocre quality, because what they were designed for – a
hands-free car phone system or small handheld mobile speakers – there is no
need for parameters which will suit the requirements of high-end audio. Their
low quality negatively influences the sound. V90 BLU5 HD is using a separate
DAC, based on the first-class Burr-Brown chip PCM1781D. The digital signal from
the Bluetooth receiver is re-clocked and up-sampled. And after that is
processed by the D/A converter.

Samplerate Converter SRC4392

A high-end sample rate converter from Burr Brown, its task
is to re-clock all signals and convert them into 24 bits and 192 kHz.
Up-sampling done in this sophisticated and clean implementation allows us to
reach the lowest distortion levels and maintain and elevate the integrity of
your wireless Bluetooth audio.

Qualcomm CSR8670 Bluetooth Chip

The majority of Bluetooth receivers use standard
“hands-free” chips. The V90 BLU5 HD has a HiFi audio-oriented chip from leading
manufacturer Qualcomm. CSR8670 is a premium-tier product, designed to deliver
high quality wireless audio performance and support the development of highly
differentiated, premium wireless audio products. CSR8670 even has a relatively
high-quality onboard DAC – also with 24/192 capability. After extensive
listening tests however, we saw that we could do better and designed and built
our own digital section consisting of a separate SRC and DAC in typical Musical
Fidelity fashion. The result was worth it, because we have probably made the
finest Bluetooth receiver on the market!

V90 BLU 5 HD is using the latest Bluetooth standard 5.0

Bluetooth 5.0 is the latest version of the Bluetooth
wireless communication standard. It includes various improvements, but only
when used with compatible peripherals. We were able to push the range of the
Bluetooth connection all the way to 240 meters (compared to 30 meters in
Bluetooth 2.0). Even with obstacles and walls in the way, we can access more
bandwidth allowing us to ensure constant high bit-rates for your aptX HD
transmission. Of course, this requires a mobile device that also supports these
standards. Should you have an older phone without BT 5.0, the standard will
still be fully backwards compatible and just fall back to previous BT versions,
albeit with taking hits in range and bandwidth.


V90 BLU5 HD is equipped with aptX HD. It was designed to
answer the growing demand for high resolution audio. This enhanced codec
supports 24-bit, high-resolution formats over Bluetooth. For aptX HD to work,
your mobile device needs to supports it too. With careful engineering and
expert circuit board design we could improve the signal-to-noise ratio,
resulting in lower background noise. Lower THD and no audible artefacts ensure
you can enjoy your music with hardly any interference. This means, we can now
enable you hear even the smallest details in your music with punchy dynamics
and transient detail on a real high-end level.

Flexible Input Extender

The V90 BLU5 HD can be integrated into any audio system,
even if there are no free inputs left. It will bypass the analogue RCA-in to
its analogue out and digital-ins to its digital outs. Then, whenever you play a
Bluetooth source, the V90 will automatically detect and play that signal
instead. If a free input is available, then the V90 can be connected in the
more traditional way and expand your range of inputs via its own analogue or
digital inputs. We have also built-in digital outputs, should you ever wish to
feed your Bluetooth source to a different DAC.
