The Nubert NuPro A200 are active bookshelf speakers (stereo) and can therefore be connected to a TV or computer directly without any additional amplifier. Each of the two speakers has its own integrated amplifier and digital signal processor. The speakers can either be connected via analog line-in, optical Toslink or digital SPDIF. Besides, there’s also a USB-DAC, which allows to connect the speakers to a computer via USB. This is particularly useful if the soundcard on your computer/laptop isn’t that good.
I have been using a cheap (20€) amplifier board for some time now and somehow felt that the audio quality was lacking.
So I once again looked around what the market has to offer in this department. Precisely, I was looking for a HiFi stereo amplifier to drive my passive 6-ohm speakers (Dali Zensor 1) in my bedroom. Due to space limitations, one of the main requirements for the amp was size: I wanted something small, not a typical huge brick of an amplifier (let’s say no more than 30cm width).
