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.

Manufacturer provided specs:

Great cable
With no other reviews I was a bit hesitant to buy this cable at first. I've seen so many other brands and sellers that sell cable that is half the gauge they claim. Or cable that is not totally copper and has tin or other poor metals in it. Especially at this low price I worried. I went ahead and bought some anyway though and figured I would chance it. For the amount of money I'd be saving it was worth it. If it wasn't as advertised I could just return it anyway. It arrived in a couple days. It is truly 1/0 AWG, and it is 100% copper. Strands packed dense but still flexible. Comes in a nice carry case. I crimped and soldered on some ends. Everything looks great and is working great. Would definitely recommend and would buy again.

Great wire.
Color: Black, Size: 15 feet
The flexibility is wonderful to work with. I used the red and black for a car audio application and it was a perfect choice for bending and snaking through the engine compartment and interior of the car. I have some just sitting on a bench and it still hasn't corroded and it's at least 3 years old. The insulation is very supple and has a nice feel to it and it carried current no problem of course.
