Real Cable Cable Bluetooth Receiver HD
High-definition Bluetooth receiver with Wolfson WM8524 DAC, aptX HD compatible, for wirelessly connecting a smartphone to a hi-fi system or amplifier.
Description
The Real Cable iPlug-BTR HD is a Bluetooth receiver designed to pick up the audio stream from a smartphone or tablet and transmit it to a hi-fi system, amplifier or external DAC. It thus allows wireless connectivity to be added to a setup that does not natively offer it.
The built-in converter is a Wolfson WM8524, capable of processing streams up to 24-bit / 192 kHz. On the Bluetooth side, the device supports the aptX, aptX HD and aptX Low Latency codecs via the A2DP profile, allowing broadcasting at a higher quality than standard Bluetooth as well as reduced latency, useful in particular for video. The stated performance, with a signal-to-noise ratio of 104 dB and distortion of 0.05%, places the device in a decent range for hi-fi use. Two types of outputs are available: analogue stereo in RCA format and optical digital, allowing it to be paired with either a conventional amplifier or an external DAC. It can store up to 8 devices and offers a stated range of up to 20 m in open field.
This receiver is aimed at those who already own a hi-fi system, amplifier or DAC of good quality and wish to add wireless streaming from a smartphone or tablet, without having to buy a new connected speaker or change amplifier. It is suitable for both a living-room setup and a more modest system, provided an RCA or optical input is available.

What to check before buying used
Test the Bluetooth connection with several source devices: unstable pairing, or pairing that no longer works with one of the 8 stored profiles, often indicates ageing of the radio chip. Also check the stability of the aptX HD stream over time, as any dropouts or crackling may reveal a fault with the receiver or its aerial. Finally, check the condition of the RCA and optical outputs as well as the power socket, which are often subject to mechanical play after repeated use.
