A small, beautifully designed device that does everything that is expected of it. I was pleasantly surprised by the quick and easy setup, the Wiim Home control application that works on multiple devices at the same time, and the contents of the package, which includes not only the amplifier itself and the power cable, but also all the other necessary cabling. There is nothing to complain about in terms of sound. Not at all for a price of around nine thousand. If a band is missing or is present in the sound, you can fine-tune it with an equalizer for each source separately. I would perhaps appreciate a little more surround sound, or the possibility of its software settings. Streaming services work without problems, as does the Bluetooth connection (SBC and AAC). The same applies to the ability to connect a USB disk. Files from the phone are played via WiFi, so the sound quality is not degraded by transmission as is usually the case with Bluetooth. Everything is controlled via the application on the mobile/tablet and is relatively intuitive. Some may be bothered by the fact that the application does not support Czech and the very fact that you cannot do without the application. For the money, this is an excellent device and you will be hard-pressed to find anything better in this category. I definitely recommend it.
