Review: Kupiłem ten wzmacniacz ponieważ ma opcję podłączenia pasywnego subwoofera. Niestety okazało się, że 100 watów mocy jaką się chwali SMSL A50 Pro być może jest dostępna, ale przy oporności 2 Ohm, więc podłączając 4 lub 8 Ohm subwoofer nie uzyskacie z niego prawie nic. Mój sub przy maksymalnej głośności wzmacniacza wydaje zaledwie cichy pomruk. Ze względu na to będę chyba zwracał ten wzmacniacz. Kolejny minus to regulacja bass treble. Nie działa ona tak jak niezależna korekcja niskich i wysokich tonów, a raczej jako "wilk eq", a więc kiedy dodajemy treble - znika bas, kiedy dodajemy basu - znika góra. Najlepiej zostawić te ustawienia na zero. Pomijając wady sprzęt brzmi całkiem dobrze i nie brakuje mu mocy we współpracy z głośnikami stereo. Plusem jest wejście HDMI eArc do podłączenia TV. U mnie to działa. Gdyby nie niska moc wyjścia na subwoofer byłby to bardzo dobry wzmacniacz w swojej klasie cenowej.
Review: Una equipo de muy buena fidelidad y sonido. Notas claras y de excelente calidad. El de odificador que trae integrado es de muy buena calidad. Lo conecte a unas bocinas monitor de 8 ohms y las llena completamente. No llega a calentarse con muchas horas de trabajo. Lo recomiendo ampliamente. No es el primer amplificador que tengo y realmente me sorprendió.

### ⭐⭐⭐⭐⭐ Review
*by K***J on 3 December 2025*

Very well constructed for the price and compact as well, I was using a digital amp with analogue controls, this amp is digital all the way with the very intuitive single rotary encoder knob and the three digit display. Once you get to know the different display menu modes, tweaking with just the front knob is a breeze. The various eq modes, bass, treble, tone presents, high and low pass filters and subwoofer volume are quite subtle to my recollection but it's well worth spending a bit of time tweaking them to your tastes as the amp has virtually no problems filling my listening room with a very balanced 3d stereo image soundstage whether using the excellent bluetooth receiver or the optical in. I have very little use for the usb dac in, 3.5mm jack in and the HDMI ARC, I have a 200 cd changer, media streamer and a linear tracking turntable connected to an Arylic BP50 preamp feeding the S.M.S.L. via an optical cable . Then out of the stereo L & R and subwoofer outputs to a pair of Wharfedale Modus Cubes and a matching pair of Mission 73ps passive subwoofers. The remote control is a nice addition and it seems to work well but my room is so small I can just reach over to the amp and use the rotary controller. I bought this amp because it had a passive sub output and an optical in - these and everything else works flawlessly - a great little modern amp for a bargain price.
