Douk Audio ST-01PLUS: a compact desktop amplifier built around the TPA3255 chip, with a Bluetooth input for phones and tablets. It's made for powering passive bookshelf speakers from a desk or small-room system, whether the music arrives wirelessly or from a wired component.
Who the Douk Audio ST-01PLUS is for
Bookshelf speaker owners: Built to power passive bookshelf speakers from a desk or a small-room system.
Phone and tablet streamers: The Bluetooth input takes music straight from a phone or tablet, so there's no separate receiver to add.
Mixed-source setups: A wired component can stay hooked up for the times you aren't streaming.
Tight desks: The compact, desktop-friendly footprint leaves room for everything else on the desk or shelf.

Douk Audio ST-01PLUS vs similar options
vs FiiO Level 1: FiiO's desktop stereo amp for passive speakers specifies Bluetooth with LDAC and Hi-Res support; pick it if LDAC wireless streaming is a must-have.
vs SMSL AO200 MKII: Built on the MA5332MS chip with balanced inputs and Bluetooth 5.0; pick it if your DAC has XLR outputs you want to use, or the ST-01PLUS if you're set on TPA3255.
vs Nobsound MS-10D: A tube amplifier design aimed at warm valve character, also with a Bluetooth input; pick it if tube sound matters more to you than the ST-01PLUS's TPA3255 chip.
