      S.M.S.L. SA400 Balanced Class D FDA Amplifier 2x STA516B MQA Bluetooth 5.0 2x230W 4 Ohm


      SMSL offers with its SA400 an excellent Class D symmetrical amplifier, integrating two STA516B amplification chips capable of developing an important power of 2x 230W under 4Ω. It also has a subwoofer output, allowing to set up a 2.1 audio system. It also benefits from a beautiful design, either by its internal architecture or its sober and modern aesthetic. The SA400 benefits from a Bluetooth 5.0 reception, allowing you to broadcast your music at a distance and with great stability. Moreover, it is compatible with the aptX codec, allowing a fast transmission, without latency, for quality close to that of the CD. The amplifier integrates many predefined equalizers. These will allow you to adapt the sound reproduction according to your listening, your equipment, or the genre of your music. The SMSL SA400 also offers tone controls for bass, midrange and treble, so you can precisely match the sound reproduction to your taste. It is also possible to adjust the level of the subwoofer output for a perfect balance. The SA400's circuitry is packed with high-performance audio components. These include two independent STA516B amplifier chips, a NJW1195 low distortion volume controller, three EQ chips, and an excellent LLC power supply with PFC and EMI filtering.

      Used the SA400 for some days as a subwoofer amp with a pair of 4 ohms bass speakers. The sound was outstanding but nevertheless I've sent the amp back. Why? SMSL doesn't mention anywhere that the amp has got a fan in the bottom side of its enclosure :-( But ok, I knew this from several tests. There is said the fan starts running at 65 degrees and stops below 60 degrees. Thought this would be acceptable (and had assumed that the amp never would get so hot in my application), so I bought the SA400. But in my device, the fan already starts after a few minutes at 40 degrees, when the enclosure still feels cool, and runs all the time til I switch off the amp. It's even running without any tone signal when there is nothing to amplify. The device stood freely in an open rack with much space around. The fan causes a permanent swoosh that is noticeable on my listening position. My query to SMSL, if this is normal or if my device could be faulty, stayed unanswered so far. But actually I already made my decision: An amp with a fan like this is no solution for me. So unfortunately I'm sending it back. Three stars for design, manufacturing quality and professional, kind service by Soundimports.

      First, if you are buying from the UK, the SoundImports pre-sales (inc Live Chat) support and help was excellent. And delivery to UK really fast. I recommend this company. As for the product - the SMSL SA400 - very impressed. As per reviews - lots of clean power with a highly detailed sound with no distortion. This amp has turbo charged my speakers. I am now looking at the SMSL VMV A2 - very similar to the SA400 but has also has digital inputs which would be very useful.
