The Stereo Box E is an integrated amplifier with phono stage and built-in DAC from Pro-Ject, sitting below the Stereo Box DS3 with more modest output power in a minimal chassis. The Stereo Box E brings Pro-Ject's considered engineering to an accessible integrated format.

Key specs that matter

One single-ended input plus a dedicated phono input are provided. Output power is a modest 21W into 8 ohms, rising to 40W into 4 ohms. Gain is 25dBu. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is under 0.12%. At a remarkably compact 206 x 51 x 115mm and 2kg, the Stereo Box E maintains a minimal, space-efficient integrated amplifier chassis.

Sound and use context

Expect an accessible, dependable amplification character reflecting Pro-Ject's broader accessible, considered Czech engineering philosophy, with the built-in phono stage and DAC covering both vinyl and digital sources directly.

Pairing

The built-in phono stage and DAC cover both analogue vinyl and digital sources directly, and the modest 40W-into-4-ohms output suits compact, notably efficient loudspeakers.

Alternatives

Pro-Ject's own Stereo Box DS3 offers a considerably more powerful alternative within the same broader Stereo Box catalogue.
