Pro-Ject BT Box S2 HD, Next generation BT 5.0 aptX-HD Bluetooth receiver, Black

Product Information

Now, we will focus on the design and functions of the preamplifier in this part of our Pro-Ject Phono Box S2 review.

Gain switch is 40dB/ 43dB60dB/ 63dB, with a subsonic switch that’s -12dB @ 20Hz. Signal to noise ratio is 85dB, THD+N is 0.01% MM | 0.05% MC. RIAA accuracy is <0.4dB | 20Hz – 20kHz. The new Pro-Ject BT Box S2 HD uses Bluetooth 5.0 and A2DP. Initially, the lossy codec SBC is supported, but this only achieves a signal transmission with MP3 quality. More exciting is that aptX and even aptX HD are also supported, so that a signal transmission in “CD quality” or even the promised hi-res audio quality is achieved, even if it is “only” up to 24 bits and 48 kHz in the end. However, this only applies to smartphones with Google Android; Apple still does not use aptX or even aptX HD for the Apple iPhone. AAC is used here, with which you can achieve about “CD quality”. Spotify Connect is supported alongside Tidal via Pro-ject’s Stream S2 app, while radio fans are also catered for via iHeart and TuneIn apps. Apple and Raspberry Pi users can use the Shairport support to connect their devices using AirPlay. Multiple steam boxes can also be stereo paired to drive an active speaker setup while avoiding unnecessary cabling, alongside multi-room support for 10 or six devices over ethernet and wifi. Up to 24-bit/192kHz data quality is supported on a single device and 16-bit/44.1kHz for multiroom applications. DLNA and UPnP are also both supported and as with the majority of Pro-Ject electronics, it is very compact, measuring just 37x103x122mm (HWD).Now, we will focus on the key features of the preamplifier, here in our Pro-Ject Phono Box S2 review.

Leveraging the increased Bluetooth 5.0 range and transmission bandwidth the new and advanced aptX HD codec sounds crisp, detailed, dynamic and excellent at all times, even if the Bluetooth connection quality momentarily drops. This avoids typical lossy compression artefacts of other codecs. The new Pro-Ject BT Box S2 HD naturally presents itself as one would expect from a solution of the said Pro-Ject Box Design S2 series. It is therefore an extremely compact product that can be easily integrated into any audio system. Aside from the unit, you’ll find an AC power adapter with a connected 58” DC cord, and three AC power plug inserts (EU/US/UK), instructions, and the unit’s user manual.

Feeding its internal Sabre ESS9023 DAC chip is a lower port count that on more expensive offerings, but there’s enough to meet the needs of most budget systems One has trusted here on all the experience in the development of electronic components and selected an analog output buffer stage, so that the connection to amplifier and speakers is as robust and solid as it can be.

All of these were more than what we had expected from a low-budget phono amp.
