Features
One Amp for All Your Sources: One reason ST-01-PRO has stayed relevant over the years is simple: it keeps your favorite sources ready in one system. Bluetooth 5.0, PC-USB, optical, coaxial and RCA keep phones, TVs, computers and players connected without swapping cables, while USB drive playback adds direct support for lossless WAV, FLAC and APE.
Confident Power for Home HiFi: Brings serious drive to your stereo system. Its TPA3250 delivers up to 100W × 2 at 4Ω for 3–8Ω passive speakers, while the included 24V power supply is ready to drive most home speakers with ease. Add a powered subwoofer through the pre-out for an easy 2.1 upgrade, or connect active speakers or another amp as your system grows.
Warm Character with Personal Tuning: Voiced around carefully selected GE 4BZ6 tubes for satisfying sound from the start, it brings a smoother character to vocals and instruments, while the warm tube glow adds unmistakable classic HiFi appeal. Bass and treble controls offer ±6 dB adjustment, making it easy to fine-tune the balance for your speakers, room and music.
Watch Your Music Come Alive: The custom VU meter gives every track a visible pulse, while AGC automatically adapts to changing signal levels, keeping the needle expressive from quiet passages to dynamic peaks. Framed by warm tube glow, gold accents and an aluminum chassis, ST-01-PRO becomes as captivating to watch as it is to hear.
Stay in Control from Your Seat: Switch inputs, adjust volume, mute, and manage Bluetooth or USB playback from the remote, while clear front-panel indicators show exactly which source is active. Clear Bluetooth pairing for easier reconnection, and toggle the 10-second no-signal auto-mute to keep idle moments quiet.
Warm tips:
1. PC-USB input also supports mobile phones that with OTG functions, but Android system needs OTG cable and IOS system needs camera kit, please prepare by yourself.
2. The ST-01 PRO uses 4BZ6 tubes and does not support tube replacement. Due to limited tube supply, the tube model may vary between production batches. Thank you for your understanding.
3.When the volume is turned down to minimum, the BT/(USB) indicator will be flashing; and when to maximum, the PC-USB indicator will be flashing; At this time, the indicator of current input channel will go out but light on when the adjustment is stopped.
