Small, cute and gets the job done
Nice little amp that's more than enough for standard domestic use.
The bass is present and powerful (depending of course on the speakers, in my case they are small KEF "Coda").
One minor problem is that the rotary knobs are not marked, which means that you can't see where they are (but a line of indelible pen and it's sorted).
In terms of amplification, there's a slight left-right balance difference at low volume, which goes the other way at high volume (also in mono signal, I'm no fool). But it doesn't really bother.
I'd still recommend it for an office, as a 2+2 home cinema amp, or as background music for a small bar or restaurant.Pro

Very good processing and sound quality of this amplifier
As a former radio electrician and installer and hirer of larger loudspeaker systems, I have some experience in this area. I was very pleasantly surprised by this mini amplifier. It fulfils or exceeds my expectations by 200% in terms of workmanship, performance and sound quality. Highly recommended.

Ideal for are price👌
(09.23) Since February 23 on 8 hours a day almost every day. It works very well and the sound is clearly audible. Coupled with a small dab radio and old Pioneer speakers.
Apres c'est pas du Marantz!! Neither is the price 😉
I recommend it for workshops and gardens.Not worth the money
The amplifier hums so loudly after a few minutes that listening to music is not possible. The device quality (knobs, rotary switches) is a catastrophe - lottery and very cheap materials.
Have sent it back.Unfortunately unusable
Unfortunately, a constant hum/buzz can be heard on connected speakers, even when no source is connected at all (so can't be from a hum loop). The controls are all very wobbly and "narrow" alarmingly when turning. Too bad, would actually be from optics / functions / price an attractive device, but is unfortunately unusable cheap scrap.

Excellent sound - precise volume control, but crackling in the speakers
Small disappointment when unpacking: one screw is in the plastic bag and another one is a worm. The holes are too big for some screws or they are too short.
The sound is excellent and very powerful despite the 2 x 12 W announced. With its reduced dimensions - there are not many on the market - one can easily find a place on the desk between the screen and the speakers. This device replaces an old one of the same size which made an impossible noise when changing the volume, which is fortunately not the case here.
not the case here.
Unfortunately, after several weeks of testing, even when I changed the location of the amplifier and speakers to keep them away from a possible source of disturbance, I could not eliminate a slight crackle in the speakers. Plugging in more speakers did not help.
As I don't know if the problem really comes from the amp - but from where else? - I lowered my rating from 4 to 2 stars.Pro
- Small dimensions (20 cm wide)
- Usable between computer sound card and passive stereo speakers
- Excellent sound
- Volume control can be done with great precision and without any noise
Contra
- 2 screws under the device do not hold
- Adjustment knobs (except volume) seem fragile and cheap
- Slight, but disturbing crackling in the speakers
Absolutely recommendable
This little thing sounds richer than my old Yamaha receiver. Hooked it up to my PC and fire up my Tannoy speakers with it. Price/performance is brilliant.

Contra
- No headphone jack
- RCA only
Does what it is supposed to do
Pro

Connected my record player to the Klipsch 51M speakers.
Very satisfied!
