- Sound controls: Independent bass and treble knobs or remote control can simplify tuning for different rooms and genres.
- Size and form factor: Ensure the unit fits your shelf, cabinet, or desktop setup while leaving space for ventilation.
- Connectivity stability: Bluetooth version and range affect seamless streaming, especially in cluttered spaces.
- Protection features: Short-circuit, surge, and thermal protection help protect both the amp and connected speakers.
