The legendary STEG K-series amplifiers are back! All made in Italy, they're as good as they always have been. Competition level stuff, as solid as ever. Super advanced monitoring options, audiophile crossover modules for the OCD type people. Fantastic value for money if you value uncompromised SQ.

When you need more channel density, the K4 amplifiers are the preferred option in the K-series. The K4.01 is the smaller one of the two, but like all amps in the series, this isn't a lightweight player. It's capable of 4x290W at 1 Ohm load stable and 2x580W bridged at 2 Ohms. Thats over 1kW of clean AB power at 0.03% THD in a single amp. And this is the smaller one... It comes with all bells and whistles of the K-series amplifiers - inaudible active cooling, AQXM2 crossover modules, remote PC management, internal ground lift noise suppression systems, regulated power supply and so on.

Works well. Id definitely use it again. Made a floating shelf to get the electronics up out of the way, and installed this power strip ontop and it works perfectly! 👌

Great product. I installed it in built-in cabinets that were installed in my office. It comes with a template, so you don’t have to measure or guess.
