SMSL AD18 80 Watt x 2 Wireless Bluetooth Amplifier For Speaker

Es de un tamaño mas pequeño de lo que uno imaginaria, aunque el truco está en que tiene su eliminador de corriente casi del mismo tamaño que el aparato, para mi mejor, no estorba y se calienta menos asi. Múltiples entradas que le otorga gran flexibilidad a la hora de conectarlo, con salida amplificada directa a las bocinas y al subwofer. Lo conecté a unas bocinas Yamaha gama media que tenia y suena espectacular. Lo compré para una tableta buena pero con sonido horrible en verdad, tanto por sus bocinitas como por auriculares, la conecto por el puerto USB para "puentear" el dac de la misma y el cambio es abismal. Ahora pasó de ser solo para redes sociales a mi centro multimedia principal, escuchas todos los detalles de la música y las películas como home theatre, solo conectalo a unas buenas bocinas y sub y suena mejor que mis auriculares sennheiser hd599. El bluetooth se conecta también sin problemas y sin lag. Muy contento con la compra, lo recomiendo ampliamente.

This amp has been my COVID special. Its on almost all the time everyday. I use it with BT from my iPad or iPhone in the morning for some quick news or a podcast. Once I get my coffee going I switch into some music via the Coax connection while I read my email. Then I flip on the TV monitor to catch the rest of the news through the optical 2 connection, which also works fine for mirroring the President's Corona Briefings. I bought an HDMI adapter for the iPad and found I get a better picture and sound than mirroring. I'll use that for movies. I don't use the tone controls very much but they boost the realism for an action movie from one of the services. The bass response is powerful enough to rattle the walls. I never had a class D amp before, this was a surprise. I have no problem with the sound quality, sounds just like my class A amps, and it's so incredibly flexible it makes a great attachment point for all my electronic devices on the long days of sheltering in place. OK, it's been 6 months and I can't tell you how impressed I am with this powerful little Amp . In the meantime I've noticed a few things. As good as the BT sounds from my phone or iPad, the coaxial connection blows it away. So much so that I only use BT for non-audiophile applications, or if I'm too lazy to plug the powered Doc into the iPad. I'm using an old Blue Circle Thingee (which was very well regarded in it's day) as my USB to Coax converter because my Peach Tree X1 is on another system. I tried an original HiFace. I didn't think it would work because it needs a driver, and it didn't. I'm going to pick up a better USB to coax converter because even with the Blue Circle I can easily hear the difference between an ALAC or 320 internet radio broadcasts and standard lower bit rate broadcast and I know a better converter is going to sound even better. For Speakers, I recycled a 3 piece Polk Satellite system from an old surround hook up and am using it for nearfield listening... and every time I listen to it it blows me away. Clear crisp bass notes and well a articulated treble. These speakers didn't sound this good when I had them connected to an 80W per Ch class A amp, (also in nearfield). I'm impressed. The only other thing I'll mention is that using the Coaxial input sounds sounds better than using the USB input. I haven't tried headphones so I can't comment on the headphone amp. So now it’s 10 months and everything is working well. I have it on a lot during the day and then again at night. After a long session, I noticed that it was warm to the touch but not hot. Never the less, with all the failures that have occurred, I’m looking around for a replacement in case my unit fails too. It’s too bad that these units fail because I really like it. The Blue Circle Thingy has been replaced with a Douk Audio U2 XMOS XU208 USB to COAX converter. Very nice upgrade. Sounds fantastic. One of the things I’ve discovered is that my iPad Pro can Bluetooth video to the TV. Not nearly as good as mirroring, which is not as good as HDMI. I ended up buy a UNI dock for the iPad which allows me to connect a wired mouse, (Bluetooth keyboard) , USB to COAX converter, thumb drives for the file system and a HDMI cable, and charge the iPad at the same time. The only downside to this arrangement is that every once in a while I forget to plug in the 60W Anker charger and the iPad batter runs down until I notice that it’s not charging and plug the charger in. Maybe I should leave it plugged in all the time.... Anyway, back to a Netflix movie... I’ll update this if it fails. It’s now 2024. The S.M.S.L AD18 never failed. I moved it to another room along with the satellite speakers and the subwoofer and it’s no longer Nearfield. My new Nearfield set up is now an RME ADI-2 DAC, 2 Genlec 8010A Powered Studio Monitors and a Genlec 7340A Powered Subwoofer. - Very Nice - The question is always, Does it sound $3000. Better? I think so, but the SMSL AD 18 is very hard to beat and the speakers are different and in another room, so it’s hard to make a valid comparison. What I do know is that the AD18 can EQ my satellites to a very close approximation of the much more expensive rig. ( But the connections have to be wired, and you need the higher Specs of the Douk USB to COAX to do it. The Bluetooth sound is acceptable, but not outstanding )

This is my 2nd AD18 from SMSL. Been using it since 2019. Buying it for a family member. Its Afforable and I got significant time-limited discount offer from Amazon, if compared buy from Lazada! Seller was fast to ship and deliver the product. Thank you FINE MUSIC and Aamazon!

That's not very quality sound but i'm happy the same.Hope this amplifier will not die fast >.<

Works good when it comes to basic functionality. Controls are hard to master because everything is with one knob. Pushing knob is not consistently picking up what I want to do and turns volume instead. When in USB mode if left turned on and I turn on my PC I get loud speaker breaking sound. This is super annoying because I need to remember to turn it off every time I turn PC off. Bluetooth can connect only to 1 device. There is no firmware update available at all. Manufacturer do not care about this model. Consider buying newer model.
