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.

Very soft
Size: Body (20" X 54"), Color: 06 - Sage Green, Number of Items: 1
The color was perfect. It’s very soft. The only thing that I really don’t like is the finish of the opening, it would be better with a zipper closure.

Super soft and worth it
Color: Light Grey, Size: 2 Pack King(20"X 36")
Honestly really happy with these pillowcases. They feel super soft and cool when you sleep on them. My hair has been way less messy in the morning too. The quality actually feels pretty nice and the king size fit perfectly. Makes my bed feel a lot more comfortable and expensive looking. Definitely glad I bought them.

SO WORTH THE PRICE
Color: Pink, Size: Queen(20"X 30")
I bought these in two colors for my new apartment with some new pillows to go on them because I got a whole new set of sheets and comforter for my bed and I have to say these are some of the softest most comfortable cooling pillow cases ever! The silk is not super great quality but for the price it's totally worth it I've noticed that it takes care of my hair better I never used silk pillow cases before... But I don't think I'll ever go back. And the zip closed with a zipper so they stay on your pillow no problem without sliding around and you having to fix them all the time they're so easy to use and they look perfect. They look exactly like the pictures! Definitely worth the price... Oh, and there's no weird smell or anything these are definitely good quality!

Helps hair health.
Color: Lavender, Size: Queen(20"X 30")
Amazingly soft, cool and comfortable. The sizes are accurate so fit pillows easily. We mixed two colors so our bed looks as comfy and inviting with stylish color blending. Hair seems happy!
