Review: Clean, powerful, and works great, inside or out. - These little guys are powerhouses. I use them out on my dock as they are sealed and also to power my indoor speakers, and the subwoofer works well. If you want enough power to fill an area well and aren't trying to blast for a concert, these work very well.
Review: Very compact ,big sound from a small package. - Good sound quality small size but didn't like that the instructions are only in Chinese. Great for desktop stereo system. I paired mine with Echo dot and 4" Dayton speakers .Great mini system.

### ⭐⭐⭐⭐⭐ Review
*by S***E on January 15, 2024*

I usually don't leave a review on the first day I use a new item, but the exception is justified in this case. I bought this integrated class D amplifier to replace a defective Topping MX3. I liked the Topping. It was a revelation when I upgraded from cheap computer speakers to Scandyna MCP speakers, an Argon Bass 8 sub-bass, and the MX3 on a Mac Mini a few years ago. However, the experience when I plugged in the SMSL SA300 this morning (USB on my Mac Mini, BT on my iPhone) was at least as great - jaw-dropping! I never thought my speakers and sub-bass could deliver such crisp, uncompromising brilliance and volume. They certainly never have before. It's like having a new music collection. The tech specs and functions are well documented; there is no need to recapitulate here (remember: no headphones connector). The amp is solid, well-made, and sits on good anti-slip rubber feet. I like the unusual form factor. It takes less space than I expected on my desk. The volume control (the crux of my old MX3) and buttons feel sturdy and high-quality, as does the responsive remote. The only somewhat odd and uncommon thing is the Micro USB connector (a cheap but working cable is included). The manual comes in Chinese and English only. If you are looking for a reasonably powered class D integrated amp with BT 5.0 and a dedicated sub-bass connector, there is probably nothing better to buy, at least not in this price range.
