The sound quality I can not judge directly, because my ears and my boxes are the best not really. In any case, the music comes as far as I can hear more or less faithfully to in the pit. Who wants a loudness switch can achieve roughly the same by turning up the bass and treble controls. In 1/3 turned up volume control device at standard line-level out of my 4-Ohm Philips boxes already provides a volume that should be audible even when the neighbors. If you can turning up a little further, the device also loosely sound for a larger living room to party volume.
At the processing can not be faulted. The unit I have not screwed to reinzuschauen, but outwardly makes everything a solid and clean impression. There is nothing wrong, and unsightly KantenDie knobs are made of plastic, which is not particularly high quality feels, but at least they do not creak, do not scratch around in the signal, and the rotational resistance feels consistent. The few connections are all placed on the machine makes sense; the auxiliary input on the front panel is practically definitely, because I sometimes like to connect the iPod. The screw terminals are in my eyes a plus, especially because they can also accept banana plugs. It should be noted perhaps that the picture shown here is slightly different from the delivered model. The headphone output is not as displayed in 6.5mm size, but as in the description of 3.5mm, also the power button is not as square as shown, but around, but I did not care 100%.
Small drawback: When I turn the unit on a blank input and close hinhöre to the boxes is independent of the volume set to hear a touch of hum, but is from about 1 m distance no longer audible to me and so for me not important ; the equipment which in my amplifier with music feed (HTPC, TV and turntable) produce far more self-noise than the amplifier itself, and the machine roars much less than the Philips-complete system that hung previously in the pits. The device itself also appears from the internal transformer easy to hum when it's turned on, but I hear even when I'm sitting at the unit and very accurate hinhöre. However, since there is also the kind of person who "allergic" reacts to something like that, I mention it again here.
Overall, I would recommend this device for those who want to grow up a decent amplifier for little money. For 100 more you get accordingly more on offer, but who simply want to dine only his boxing is also well served here.
