Stereo Audio Amplifier S-288 Bluetooth 5.0 - Compact 4.0CH HiFi

In this review of the S-288 stereo audio amplifier the bottom line is clear: this compact 4.0CH HiFi receiver is best for homeowners and hobbyists who want tidy, powerful amplification for multiple passive speakers without a large rack unit. The S-288 pairs a small footprint with Bluetooth 5.0 convenience and useful tone controls, and its combination of four speaker outputs at 40W each and a peak power headroom makes it a practical choice for multi-room background music, small home theater setups, or outdoor gatherings where portability and simple setup matter.

Key Features

• 4.0 Channel Output: Connects up to four passive speakers and delivers 40W x 4 rated power for even distribution across zones or stereo pairs.
• Bluetooth 5.0 Wireless: Built-in Bluetooth 5.0 allows quick pairing with phones, tablets, and TVs and reduces wiring clutter within about 5m/16.4ft.
• Multiple Inputs: RCA, AUX, USB and SD support makes it easy to play from legacy sources or a USB drive without adding extra boxes.
• Tone Controls: Combined treble and bass control knobs let listeners quickly tune sound character for clearer highs or deeper bass depending on speaker choice.
• Compact Design: The mini size (7.1 x 4.1 x 1.7in) keeps the amplifier unobtrusive and portable for indoor and outdoor use.
• Microphone and FM: Mic input and an FM tuner with auto-scan and station memory expand functionality for karaoke and local radio listening.

Who It's For

The S-288 suits homeowners, hobby audiophiles, and renters who want to power multiple passive speakers without a large receiver. It is a good match for living rooms, patios, or small home theater spaces where Bluetooth streaming and simple physical controls matter more than separate component ecosystems.

Those who should look elsewhere include listeners who need very high-end audiophile performance or advanced room correction features; the S-288 is designed for practical HiFi use with low distortion but is not a replacement for full-sized audiophile amplifiers with extensive DSP or networking features.

Pros & Cons

Cons

• Bluetooth range is limited to about 5m/16.4ft, so placement matters for reliable wireless streaming.
• Not intended as a high-end audiophile amp with advanced room tuning; tones are adjusted with simple treble and bass knobs.
