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.

High dose Metabolism support, trusted brand
Size: 60 Count (Pack of 1)
This is my second bottle, and I’ve been happy with it so far. I tend to stick with brands I trust, and I appreciate that this one is made in the USA and does third-party testing. It gives me a little more confidence in what I’m actually taking. The capsules are easy to swallow, and I like that you get a higher dosage in just two capsules. I take mine at night as part of my routine and I never experience any after taste. Overall, it’s been a good, consistent product for me, and I plan to continue using it.
