Original Review

Okay, I need to preface some things here. First I have been in the electronics industry my entire adult life. Next, I am picky about sound. And last, I put this device in a system for a friend that has some really neat components and others a little eclectic. Here is the system; A pair of Revel 6.5" bookshelf speakers (awesome!), an old MTX 12" subwoofer (from the 90''s), an Echo Dot, a 55" TV, a Roku, and a bluetooth source (usually my cell phone). So, we have compressed sound from every source, not exactly the best reference, but in today''s world, a pretty common thing. The sound from this device is ample, when coupled with the 12" subwoofer, it has room filling sound and is impressive. As far as sound quality, it is better than I expected (maybe the Revel speakers are helping here?). I am not a Class D fan, but this device was purchased with one thing in mind, size and it is small! So it gets 4 out of 5 as it fits exactly what I needed. Now for usability, it is ok. The remote is not really intuitive and the display is fairly small, you can''t see it from across the room (at least I can''t). It would be nice to have the remote function in a way that you select the source directly instead of a toggle? If you are using this on a desk, no issues. The unit seems to be reliable, sounds good enough, powerful enough, and is compact. In the system it sits sideways just under the edge of the television. No big components to hide here. The cost is near that of some AV Receivers, but again, size was my concern. Hope this review helps!

***UPDATE***

The Bluetooth and the Optical input failed! The analog parts are still operational, but who cares? The cool part was the optical from the TV and linking my phone. Now it is an overpriced amplifier that does not have the features I wished for. I requested a refund and it appears I am outside the "window" and it is an 80% refund? GRRRRR!!!! I am on with Amazon customer service as I write this. There are SOOO many more options than this device at just a little bit more money. I just didn''t want to go to a full on AVR, but it appears that this is what I am going to have to do. To put this in perspective, I can buy a Sony AVR that is a refurb for $179 which adds surround, HDMI switching, AM/FM etc. So lesson learned. Amazon is going to refund the extra 20% and I am happy with that, just not this product. It is not ready for primetime in my opinion. Ordering the Sony today! Was nice while it lasted, going to waste the "real estate" on a big old AVR instead. Hope this review helps.

I’ve had the SMSL for a few weeks now. I hooked it up to my Bose 301’s expecting it not being able to push them very hard. The reviews I had seen were it powering much smaller bookshelf speakers. Let me tell you..... This thing is incredible!!!! Not only did it push my 301’s but it pushed them HARD!!! I have nice floor standing speakers also. I almost feel like the SMSL AD 18 would power those as well! This unit is very solid with great build quality. I have had no issues with it yet. I am having a hard time putting into words just how impressed I am with this little powerhouse!! I have shown it off constantly and everyone has been impressed with it as well with eye popping and jaw dropping results!!! Also... the Bluetooth is incredible! I pumped up the volume and walked all around my whole house changing songs and volume levels on 2 floors (not including my basement) from end to end top to bottom with NO issues what so ever! In my photo the SMSL is to the left of my PS3 (yes I still play it... Lol)
You will not be disappointed with the SMSL AD 18 if you decide to purchase one!!!

Update.....
I’ve hooked it up to my 10” powered sub. 8th inch headphone jack to red side (mono) rca. The ad18 runs it great!!! I let it play for a while with some hard hitting bass to see if the unit heated up. It ran a little warm but nothing to be concerned about. I had the volume on my phone at full with the volume on the unit at 20. I think the bass on the unit is at 4. The sub was set to about 90 hz. And regular polarity with the sub volume a little over quarter way up. Still very impressed with this little power house!!!

Update #2
I had the AD running optical from my cable box which was great. Come to find out my Samsung TV has Bluetooth and can search for devices. I searched and found the AD18 and paired no problem. Even better I can control the volume through my Samsung remote now. I just leave the AD18 on because even though it’s paired with my tv, evertime I turn off the tv it disconnects. So leaving it on means all I have to do is connect to it beings that it’s already paired which is fine. I’m still amazed at this little power house!!!

Hi! The SMSL AD18 is actually an incredibly good little amp. I have used it with predominately with Bluetooth and USB as a source. I have used it with all sorts of speakers, ranging from martin logan electrostatics and large MG-IIIa''s all the way down to tiny bookshelfs. So far, it hasn''t had trouble powering anything that I throw at it, with good sound as well. According to all of this, this amp would and should get a 5-star rating as it truly would deserve it outside of a very serious flaw.

I honestly do not understand exactly why this happens, but it is incredibly frustrating and is damaging my already existing equipment. The amp is primarily used through USB, set at 48 kHz (although it used to be set at 96 kHz). Not very often, but often enough, I''ll be playing a game, or just listening to music and the amp will instantaneously pump out insane amounts of static to the point to where it hurts my ears. There is nothing to indicate this will happen and it is quite sudden. Anytime this has happened, the USB port it is connected to immediately dies and no longer works. As a result, I have had 4 out of the 7 ports on the back of my $350 motherboard die. This has happened with my headphones on, as well as when using speaker outputs. This is very likely to damage ears as the sound is well over 100 dB when it happens.

If I were you, I would wait until SMSL ore some rep decided to address this issue as it is not worth losing your hearing or have your equipment damaged due to a simple flaw.

Not for me. The amp was loud enough and reasonably well made but all the magic and excitement t of the humble hybrid tube amp it was replacing had vanished. That tube amp got fried somehow after 3months but I didn''t realize how awesome it was until it''s digital replacement, this SMSL AD80, arrived. The music from the SMSL sounded just so blah that by the third day i couldn''t take it and packed it up and back to amazon it went. Also I should point out in particular that I am mighty skeptical about that strange sub woofer out port. The sound coming out of my powered sub was so quiet and such a shadow of what it had been with the tube amp that I was afraid my subwoofer got fried along with tube amp. But when I split the signal off from a pre amp to the sub it was back to its thunderous self. So maybe mine was a defect but the sub out on mine was close to non functional. Also..... The EQ settings must be mentioned. So I went to college in the mid 90s when the Aiwa all in one sound system haunted us college kids with terrible performance and sound. The most detestable aspect of all on those (and there were many) was the pre set EQ settings where each one made your music sound progressively worse. Inna nutshell, little has changed. "Jazz" with actual jazz was worst of all On this SMSL btw. Anyhow, "no eq" was alright. And the music was loud and it was clear enough. It just wasn''t the same captivating music full of depth and sparkle and shading and texture and nuance and detail etc.... I have been spoiled by the tube amp sound and there is no going back. I should also mention that I was running two vacuum tube pre amps into the SMSL and I thought that would be enough to give me the sound i was looking for plus all the benefits of a digital amp. However it simply didn''t work for me. Also everything was quite hard to read on the tiny screen. Like I said though, the unit was well made and the many good reviews attest to its usefulness for many so I don''t want to be too harsh. It just did not work for me.

I wanted this ever since I first saw it here at Amazon. I need to organize my tv and audio listening devices but a full-blown A/V receiver is overkill in my case. This amp does everything I need in a super small box. Some of my preferred features that don''t appear together on many others are Bluetooth w/Aptx, optical in for the tv, a very readable display, and the intuitiveness in using it. It''s good that it is so easy to use because there isn''t really a manual. I mean, there is, but it''s brief and may not even be in English (don''t know - didn''t look at it much).

The longest part of getting it up and running was fitting my speaker cable with banana plugs. You don''t need to do that, but why wouldn''t you? I used the aux jack with my AT LP120 turntable and plugged my computer in to the micro USB (this comes with a USB A to micro). The internal DAC seems to work really well. With such a small amp I''m not limited on where I can place it. One note - I think the remote works on line-of-sight so there''s that slight limitation.

So far so good. I''ve had it about a week so far. It''s driving a pair of Fluance SX6''s and a 10" Polk audio powered sub. The Bluetooth works flawlessly and easily. I assume the Bluetooth has the newest tech considering how well it sounds. I''ve been playing 320kbps mp3s with the Bluetooth. Bluetooth seems to be mixed louder than the other inputs for some reason, but not enough to be a nuisance or anything.

The "aux in" works great.

The optical works great as well.

I haven''t used the USB out yet, buy I''ll go ahead and assume that it works well too.

My only complaint and the reason for the 4 stars instead of 5 is that during dry winter months, the static you build up walking on carpet can cause problems. Anytime you touch the unit without grounding yourself first, the unit will drop the audio output regardless of the input. You have to turn the unit off and then back on. Luckily it comes with a remote. I may try to ground the unit a little better myself later on, but until then I can deal with the static issue. It''s probably not the best thing for the unit, but I''ll consider my troubles a test.
EDIT****
SIX WEEKS IN, THE ZAPPING ONLY PRODUCES AN AUDIBLE POP AT A LEVEL BELOW THE LEVEL OF THE AUDIO. IN MY EYES, THIS IS AN IMPROVEMENT. I DIDNT DO ANYTHING TO IT. THERE FOR A WHILE, IF I TOUCHED ANYTHING CONNECTED TO THE AMP AND IT ZAPPED, THE AUDIO WOULD CUT. WHETHER THE TV, XBOX, OR RECORD PLAYER WAS TOUCHED. ILL BUMP MY RATING UP TO 5 IF IT LASTS LONGER THAN A YEAR.

Well worth the money. Would recommend.

EDIT****
IF YOU THINK ITS BROKEN, CHECK TO MAKE SURE OUTPUT IS SET TO SPEAKERS AND NOT HEADPHONES. THAT''LL SPARE YOU OF ANY EMBARRASSMENT, IF YOU KNOW WHAT IM SAYING.

I''m using this coupled with a pair of Denon bookshelf speakers and a Yahama subwoofer. It sounds pretty good for a tiny, cheap amplifier. Compared to the full-size Denon amp I was using until now, the bass is a bit weak from ordinary speakers, and it really needs the subwoofer to fill out the low frequencies. In addition, the middle frequencies sound a bit harsh to my ears but, again, that''s in comparison to my previous amp. The USB input appears as a USB soundcard, and does need any specific drivers on my computer. The Bluetooth connected to my Sony phone without difficulties, and was recognized as an AptX device. The unit is smaller than it looks in photos -- about the size of a house-brick cut in half lengthways. It needs an external power adapter, which is about the same size. I was irritated to find it was supplied with a European plug, not a UK one. This isn''t a deal-breaker, but it means adding a couple of quid for an adapter or a replacement plug to the cost. It is supplied with a short USB cable which is, oddly, white. There is an external Bluetooth antenna -- presumably because the all-metal casing would prevent an internal antenna working. Geeky technical note -- this unit uses class D amplification. This means that the amplitude of the output signal is controlled by pulse-width modulating (PWM) a current which is either fully on or fully off. Thus negligible power is dissipated in the final output stage which, presumably, is why the unit can be so small. It also means that no separate DAC is needed for digital input signals -- the digital sample values are converted directly to PWM duty cycles. It also means that the analog input has to be converted to digital. There is therefore no conceivable benefit to using this unit with an external DAC feeding the analog input, as is the case for many traditional class-B amplifier designs. Class D amplifiers do tend to have a characteristically "digital" sound -- bright and a little harsh. However, the signal-to-noise ratio is impressive, because there is no analog processing whatsoever. All in all, a good purchase, if you need a very compact amp with direct digital inputs and a subwoofer output.

Power on a budget.... I had this hooked up to my iPhone and passive Mission 100 watt speakers in minutes. This is not a Class A high fidelity item - but for what it is, it''s extremely good (which is why I''ve given it 5 stars). Bass sounds warm and controlled, mid range is clear and the treble is a little splashy and harsh if adjusted from the neutral. But it packs a big punch through 8 ohm speakers - plenty loud enough for most applications, and I listen loud! My application is an outbuilding at home and I''m very happy this will do just what I need. I have some doubt how this tiny amp will cope with heat sync (lack of) over extended use - but I have nothing to back this up.... merely it''s small size and power. I should add that it comes with a substantial power brick which is the same size as the entire amp.

This amp produces clear and powerful sound with my 15 year old Acoustic Energy 109 floorstanding speakers and 5 metres of QED cable. I use the optical to connect to my TV (my £300 ARC sound bar and sub caused lip sync problems that I could resolve) and Bluetooth with my iPhone for music. The amp fixed the TV lip sync issues. As for music, with the amp at volume 23 and iPhone volume about 3/4 it shakes my 10m x 5m lounge so could easily work for a house party. With this amp I tried the What Hi-Fi 10 songs to test your speakers and my setup ticked all the boxes. Likewise songs that I have listened to for years have detail I have never heard before. I’m not an audiophile, I have just been buying hi-fi kit for 30 years and a £120 amp with15 year old speakers and £10 speaker cable blows everything else away, IMHO. It’s a pity these class D amps aren’t taken seriously by the press.

I''ve been wanting to upgrade the sound system for my PC for a while and have been pondering whether to go for powered speakers or Amp driven ones. Having found this little Amp and its good reviews I thought i''d go down the route of Amp driven. The set up is from the computer sound card into the amp and onto the Wharfedale Diamond 9.1''s. The power the amp supplies is plenty to drive the speakers comfortably at low and high volumes and it sounds as good as an entry level Intergated separate amp so the price of £122.99 seems reasonable. The Amp comes with a power supply that looks similar to a standard PC type PS, but this one is a 24V 5A - which makes the claim that the amp is 2 * 80 watts unlikely, as the max power consumption is likely around 120 watts. 20-30 per channel is more likely, but even so it still packs a punch and is perfectly good for a PC/TV set up where space is a key consideration. Aux from the PC, Optical from the TV tested and work well, and I''ve just tried Bluetooth and my Huawei P10 Lite connected first time and the sound is good. I''ve included the User Manual for those interested in the technical data and operation. The headphone output is okay, but as others have noted it does have a limited output, so if you have high impeadance phones and want to listen loud you may want to think about a headphone preamp. The remote control - it works and does the job, but not exactly elegant. Overall though i''m really pleased i went for this set up over powered speakers

===EDIT=== Despite the product description claiming it''s supported, there is a problem with this amplifier and the 96kHz USB sampling rate, where every so often the speakers will output a deafeningly loud cracking/hissing noise. This can be resolved by setting the sampling rate in windows back to the default 44.1kHz sampling rate. ========== I bought this wanting a compact, Bluetooth-enabled amplifier that would compliment my Wharfedale Diamond 220 speakers without breaking the bank while also not being so incredibly cheap the quality is in question. I''m a student so the limited space of my student bedroom meant I was looking for something with a compact package. I managed to get a relative bargain by getting a customer return from the Amazon Warehouse, thankfully it was in perfect condition as I''ve found the warehouse to be a bit hit-or-miss. The unit has loads of connectivity, I opted to use the USB connection (configured at 96kHz) from my laptop as this would bypass my laptop''s sound card and instead send the digital signal directly to the amplifier. I connected my speakers up with some speaker cable bought from Richer Sounds and some soldered banana plugs from Amazon. I''m very happy with the sound, my speakers are rated for 50W each and this amplifier can go up to 80W per channel. This amplifier is **loud**, and I''ve gone nowhere near the limits. The proprietary ''SDB'' EQ mode makes for a good listening experience, I also did a +2dB bass offset because I don''t have a subwoofer (although there is a port for connecting an active/powered subwoofer in the future). I''m no audiophile but I think it sounds pretty great! The Bluetooth interface supports APT-X, a low-latency audio codec. My phone and laptop both support this, I think it sounds fantastic too. This is great if I''m watching movies in bed from my laptop as I can avoid using my laptop speakers, I do notice a tiny bit of lag where the audio is behind the video. (With VLC video player you can set a delay on the video if this annoys you). The display is good for configuring the amplifier, it works well and is intuitive enough. The remote is nice for controlling the volume and settings from in bed, however, the remote leaves a little to be desired... Sometimes the amplifier doesn''t respond to button presses on the remote, so you have to press ''A'' to sync it back to the amplifier. The remote won''t allow you to change to modes without direct sight of the display because there are no buttons like ''Bluetooth'', ''Aux'', instead there''s a button for switching between inputs, but you can''t tell which is selected without sight of the display. If I''m in bed and want to switch from ''USB'' to ''Bluetooth'' it''s hard to read what the display is set to from that distance. Overall I''m really pleased with this amplifier. It''s small, affordable, well built, sounds great and has great specs.
