Customer Reviews (4.0 / 5 · 5 reviews)

Evelyn ★★★★★

The pre-amp mode made integrating it with my powered speakers effortless, and the eight-core XMOS handles everything smoothly. Sound is noticeably cleaner than my old setup.

Edward ★★★★★

The LDAC over Bluetooth sounds surprisingly close to wired, which I wasn't expecting from a desktop unit. Running my headphones off the amp it drives them with zero background hiss even at higher volumes. Genuinely happy with this thing.

Claire ★★★★☆

I’ve been using it with LDAC from my phone and the sound is noticeably cleaner than my old setup. The pre-amp mode works well for controlling powered speakers, though the volume knob feels a tiny bit loose.
