The reproduction quality is there, and using HD files gives a convincing result. However, Bluetooth cannot reach the quality obtained with a network player connected via Wi-Fi. The Pro-Ject BT Box S2 HD receiver is certainly the best Bluetooth receiver in its category.

FAQ: Everything you need to know before buying the Pro-Ject Box S2 HD Bluetooth receiver

What is the Box S2 HD Bluetooth receiver for and what sound quality does it offer?

This small receiver lets you connect a tablet or smartphone via Bluetooth to an existing amplifier, offering high-definition sound quality thanks to the aptX and aptX HD codecs. Bluetooth cannot, however, reach the quality of a network player connected over Wi-Fi, which remains the inherent limit of any wireless transmission. Find it in our audio sources section.

What outputs are available to connect it to an amplifier?

It has two outputs: a Toslink optical digital output to connect to your amplifier's optical input, and a stereo RCA analogue output to connect to an "aux"-type line input. This dual output lets it suit almost any amplifier on the market.

How many devices can be stored and what is its range?

It can store up to 8 different sources, such as a smartphone and a tablet, which avoids having to re-pair the device each time you change source. It works over a distance of up to around 10 metres thanks to its included antenna, and runs on Bluetooth 5.0 with the aptX, aptX HD and SBC codecs.

Is it a good solution to modernise an old Hi-Fi system?

Yes: this small box lets you add high-definition Bluetooth streaming to any existing amplifier, without replacing the whole system. The aptX HD quality is clearly superior to classic Bluetooth. It is still recommended to prefer a wired connection or a Wi-Fi network player when audio quality is the absolute priority.
