Today, I’m excited to introduce two fantastic headphone amps: the Campfire Audio Relay and the Pro-Ject Head Box E, both designed to provide top-tier audio experiences, whether you're on the go or at your desk.


Pro-Ject Head Box E: Compact Yet Powerful

The Pro-Ject Head Box E is the more affordable option of the two, priced at just £89 ($120). Despite its modest price, it stands out due to its use of

discrete components instead of integrated chipsets, delivering a surprising audio performance.

It provides 665 milliwatts of power into 32 ohms and features two headphone outputs (6.3mm and 3.5mm) for shared listening. It also includes RCA outputs, which allow unaltered audio to be sent to your hi-fi system. Pro-Ject claims that this compact amp "outperforms the headphone stages typically found in larger, more expensive amps," making it a great option for anyone looking to enhance their sound experience.

Campfire Audio Relay: Portable Powerhouse for Mobile Audio

On the other hand, the Campfire Audio Relay is a USB-C DAC/amp designed for those on the move. Priced at £229 ($299), it's a compact yet powerful device that’s ideal for audiophiles who need portability without sacrificing sound quality.

It features the AKM 4493 SEQ DAC chip, which adds a touch of analog warmth to the sound. The Relay supports both 3.5mm and 4.4mm balanced outputs and offers features like selectable high/low gain

, six filter modes, and 32-bit/768kHz resolution, supporting both PCM and DSD playback. With these advanced features, it’s perfect for both casual listeners and those who want more control over their sound quality.
