awesome amp, does exactly as told and sounds amazing
ByGuang wenSaturday, 16 March 2019
Product is good. Works fine. Good build Quality so far. Display has light bleeding from corners if you look from above. Like when the amplifier stands on your desk. If you look straight on the display looks good. I ordered to Switzerland and got a German SchuKo plug. It is no big problem because I can use another cable. Remote control works good and seems like it ihas decent built quality with good pressure points on the buttons. Volume control wheel on the amplifier unit is solid and clicks into place firmly for every step. Bluetooth works fine with my smart phone. I like the fact, that you can select the output from speaker to headphone manually with the remote. If you have selcted headphone output, it won't switch to speaker output when you disconnect the headphone plug and vice versa. Soundquality ist good in my opinion. I can not hear a difference to my old ESI Juli@ with headphones (AKG 701) plugged into my stereo amp (NAD C320 BEE).

Cant believe I waited so long to order it Sounds great very powerful for such a SMALL device runs as a 2.1 setup in my master bed room will buy another if I need another amp
ByHaluskaWednesday, 13 March 2019
I had problems with my power suply but the seller agreed to send me a new one. The sound quality i very good. It can do 24bit 192khz from PC. But you have to always use PCM on every device. No Dolby or DTS but it is stereo so PCM is the best anyway.

A Great budget amp. Really small package. Not all the features in the world, but if it has what you want, go for it. Arrived much quicker than expected (christmas)

Good amp. Drive properly my focal electrtra 1027 s
ByQualizzaSaturday, 02 March 2019
Fast shipment from Germany to Sweden. I was hesitant at first buying this amplifier. It's really small and neat. I tested with two different bookshelf speakers. It blew my mind that they drove those in an impressive manner. For smaller setups this is a no-brainer. This is the second smsl product I have. I think I've found my hifi brand and look forward for next purchase.

This amp was a replacement for my retro Onkyo Reciever, to be used with my PC to power a Canton Sub and Satelite Speaker. In addition I was looking for a amp, which could power my gaming headset better than the Asus Mainboard. The sound quality is great for the prize, basically there is no difference to the Onkyo receiver I have used before. It is very easy to use, basically there is no need to look into the manual (which is actually quite good). The headphone performance is much better than the onboard sound, clearer, more base, more stage and more details. I am very happy with this amp and would buy it again. Clear

There were tracking notes, but it came in 20 days, took it to the post office, the address of the chinese did not specify, only the index, the benefit of the track was correct. The amplifier is even.
ByGorkaThursday, 28 February 2019
An excellent amplifier, to be honest, then i did not even expect such a quality and at the same time a powerful sound from such a baby!... I bought for the sound of the projector through bluetooth as a replacement of muses. The center which has already become not functional for 19 years of use, the speakers themselves 80-watt din, for the whole volume is even scary to give, i'm afraid that the speakers will not withstand, in short the order is very satisfied and i recommend everyone! Thank you to all the employees of this store!
ByAndreassenFriday, 22 February 2019
Very good quality! Universal audio plug!
ByUsatayaFriday, 22 February 2019
Very satisfied, well protected, the volume button to a little games which is a pity, bass deep and powerful, nice aesthetic, congratulations to the builder.

Received in a week. Good product. Tested for others to you.
ByAdamWednesday, 20 February 2019
ecieved the wrapped package within 2 weeks after 11.11 The unit is small. Connect to my 100W traditional tower speaker and use BT connection. it works perfectly. sound very good. Unit a bit warm after long usage.. so may need ventilation. Will test on USB and Optical when there is chance...may not have the chance give feedback.
ByPanicekWednesday, 20 February 2019
Item is good!but i do not think is 80w but 50W.Sound quality is above average 8/10 compare to any japanese unit.I am using mission m70 speaker.The bass is good.Keep it up!The advantage of this unit is so small and powerful considering it size.If you need a small a powerful unit and reasonable cost.This must be the unit.
ByСабенинSaturday, 16 February 2019
l read that it was small .But l was still surprised when l took it out from the box. Paired with a set of Polk Tower speakers. The sound is as good and spacious as my previous Yamaha receiver. For this price l am very satisfied.
ByGennadevichThursday, 14 February 2019
Great little amp, a lot better than my previous HT system from Samsung. Very good sound quality over Bluetooth. Now I need better speakers. It feels a bit cheap, I guess you get what you pay for. A similar product from nad or Denon would cost more than triple the money so I'm satisfied. Shipping was extremely fast from Germany to Sweden.
ByMatveevFriday, 08 February 2019
ransport tock forever, but the wait was well worth it, the tiny amp have more power than I hoped for. Played nice and clear along with a pair of Genexxa LS-266 (twin 6” and tweeter, 4 Ohm). Sound is detailed, with surprisingly good bass punch, but a bit metallic hard unpleasant sound in high vocal frequencies pull the total experience down some. Whit a bit warmer touch in midrange, this amp wold be competitive with far more expensive hifi amps, all in all a great amp for the money. Also tried the amp with some bigger hifi speakers just for fun, but 4x8” proved way to much to handle for this little amp :) Highly recommended to drive relatively small speakers, with nice well working controls.
ByVladimirSaturday, 02 February 2019
This amp is a little powerhouse! It looks great, works great and sounds great. Power brick is a bit large, but it's not an issue. It's easier to hide that than find place for huge amplifier. The only complaint I have is the volume knob/potentiometer on the front. It's very flimsy and skips steps sometimes. It was very well packaged as well, not even the outer box was damaged.
ByVitalyevichSaturday, 02 February 2019
Very nice product. Actually I use it as a pre-amplifier via head-phone output. Works exactly as it is in describtion. Quality od headphone outputis very good. Only one negativum from my point of view - when somebody connect to Bluetooth, nobody else is able to connect till the first user manualy disconnect on the phone. Hopefully SMSL will release some update to correct it. For example on my JBL Flip4 when somebody else try to connect via Bluetooth, it automatically disconnect the first user - it’s a very helpful feature.
