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:

Misinformation!
Color: Dark Black, Color: Dark Black
Be aware that this does NOT ship with a class 4 gas lift. The whole reason I bought this chair was because it shows in the advertising this comes with a class 4 lift. Have contacted the seller and gotten the "we have a 1 year warranty" line. I am in the 300+ lb weight class. I have had many MANY other class 3 lifts and I know it will work as intended for about 2.5 years, and then it will slowly fail and not be able to stay up.

Nice and Sturdy. Great quality
Color: Dark Black
This a very well built sturdy chair. It was easy to put together and it came very fast in the mail. I have had 2 other office chairs made by other compaines and they were nice but they both seemed a little loose and not solid enough. they all lasted less than an year. This one is solid, well built and will likely last a lone time. It is easy to adjust also. Its nice and wide also.

Great find!!
Color: White Rose Velvet, Color: White Rose Velvet
This thing rocks. I hope it lasts longer than my last gaming chair bc it was double the price. It arrived days earlier than estimated, is soft, comfortable, and really pretty. I did not love the instructions, but I figured out assembly without too much trouble. It reclines without falling over and goes up and down smoothly. My cats immediately love it, so I’m really happy! Let’s hope it withstands longevity.
