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.

The cutest!
Size: One Size, Color: Gold-tone Hardware/Mk Embossed Glitter/Crimson
Happy with my purchase! If you are looking for a small yet cute wallet this is for you! I put just the important items (ID, couple cards and cash) it’s great to throw into a sling bag and go! Doesn’t take up too much space yet is cute to carry! Got a compliment at the store by the cashier about the slight glitter hue it has!

So cute
Size: One Size, Color: Silver-tone Hardware/Light Sand
Cutest little wallet for when I carry a small purse. For just a few of the things, it's perfect. Its the Michael Kors quality you'd expect. Highly recommend if you only want to carry your drivers license and a couple of cards
