Douk Audio ST-01 PRO Bluetooth Amplifier With VU Meter

The Douk Audio ST-01 PRO is a Bluetooth-powered amplifier that still manages to channel the design cues of the classic rack amps of the ‘60s. That’s thanks to the genuine VU meter with backlight situated right on the front of the unit—and because Douk Audio has also built in a sensitivity adjuster, you can really dial in the visual accent of the VU meter to your tastes. Softening the modern amp sound, there’s a set of tubes inside to add a bit of extra vintage styling and warmth. But don’t let all those classic audio choices fool you, because there’s a ton of modern functionality on display here. The Bluetooth 5.0 functionality makes for easy wireless connectivity with your modern audio devices, and the U-disk format support delivers compatibility with mp3, Wave, WMA, FLAC, and APE formats. You’ll also find coaxial, optical, and USB input options—the latter featuring up to 96 kilohertz, 24-bit resolution for impressive DAC functionality as well. Just next to these ports, the ST-01 Pro puts more control right at your fingertips with 6-decibel bass and treble adjustments to really dial in the sound.
