Review: Best ever - What an amazing product. It is sensational
Review: Absolutely phenomenal - SMSL A300 HiFi Power Amplifier Review The SMSL A300 is one of the best examples of how far compact Class D amplifiers have come.

The SDB sound modes offer subtle but effective tuning options depending on your preference. The included remote is straightforward and responsive. The build quality is solid, the interface is simple, and the amplifier runs cool even after long sessions. Final Verdict The SMSL A300 is an excellent all-around amplifier that combines high output power, low distortion, and modern convenience in a small and dependable package. Its clean sound, strong performance, and ability to power a full 2.1 setup make it one of the best values in compact HiFi equipment.

### ⭐⭐⭐⭐⭐ Best Class D amp I have tried
*by C***S on 22 November 2023*

MY USAGE: I use this amp with my vintage Mission Freedom speakers and a Modi+ DAC. Wow! This amp easily produces 85 dB of full range sound with punchy lows and smooth high frequencies. It replaces a generic Fosi Class D amp. Surprisingly large upgrade for only a few dollars more. WHAT I DON'T USE: - I don't plan to ever use the Bluetooth input. I want CD quality or higher sources so BT is never on my list. - I won't be using the USB input either. I like my external DAC and route all digital sources through it. - I have no plans to use bridge mode. PROS: - Enough power to produce 85+ dBA in my 20' x 20' room with circa 1985 floor standing speakers. - Decent EQ presets. Includes "tone control" EQ option where you can customize bass and treble. - Overall sound is better than the half dozen other Chinese Class D amps I have tried. IMHO: All these amps were decent. This one is just better. - Good IR remote. Simple access to every feature. - The menu system is surprisingly straight forward and easy to navigate. - Amp quickly powers up to last chosen input. Silent start up (no speaker woof!) - like it should be. - Display always returns to showing volume number (out of 60). Big enough to see from across the room. - Two RCA inputs are nice-to-have. Handy for doing quick A+B source comparisons. CONS: - Two character display makes it hard to decode things like EQ mode and a few other settings. But that is also part of the fun :). I needed to read the 5 page manual to figure out all the options. - I would have preferred a proper volume "knob". The recessed thumbwheel is just OK. I use the remote 95% of the time so no big deal. - Like most cheap Class D amps: No balance control.
