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.

The K2.03 is the 2nd most powerful 2-channel amplifier in the K-series, capable of 2x875W at 1 Ohm load stable, 1x1750W bridged at 2 Ohms or 3500W at 4 Ohms strapped in serial power mode with a 2nd amp. Thats almost 2kW of clean AB power at 0.03% THD in a single amp. And there's even one more step up from this monster in the K2 lineup, which is insane in its own right. 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.

Wonderful product but only half full
Color: #02 Champagne Gold, Size: 0.17 Ounce (Pack of 1), Color: #02 Champagne Gold, Size: 0.17 Ounce (Pack of 1)
I love this product but I'm incredibly disappointed the bottle is only half full. It is not sticky and has a beautiful spray distribution. It is easy to apply but also appears the glow fades easily. This product is incredibly functional and beautiful. 5 stars if it was a full product
