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 K4.02 is the larger one of the two, no small feat when talking about the K-series. It's capable of 4x420W at 1 Ohm load stable and 2x840W bridged at 2 Ohms. Thats way over 1.5kW of clean AB power at 0.03% THD in a single amp. A good mate with the K2.04 in their loveable unnecessariness, 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.

Sturdy and well made
I have yet to use this jig, but on initial inspection it is well made and no doubt will withstand a lot of use. The machining of the threads was rough on the one I received, but after screwing in the guides a couple times the operation became smoother. Probably lack of cleanup after anodizing left in the threads. Other than that it looks like it will be useful and longer lasting than many of the plastic jigs out there.

Easy to use
I built a bookshelf for my grandson and wanted adjustable shelves. This jig did the trick. Very easy to use, and a lot of adjustability. I have other tools by goingmake and they all are well made and affordable.

Works very well and holds up over time!
This works really well for drilling out shelf pins! The drill bit that comes with it is a good quality bit, and the holes in the metal block are very strong, The drill bit doesn't even come close to cutting into them. I have drilled about 1000 holes with it so far, and it still works as good as it did when it was brand new! I would definitely recommend this over the plastic ones. It's very easy to use, as well.

Great item
Size: 9 Holes
Works great Would be nice to have another peg to make sure it stays in line. Just used a drill bit of the same size. Worth the investment

Game-Changer for Clean, Accurate Shelf Pin Holes!
This shelf pin jig absolutely delivered on everything I needed — the ease of use was fantastic right out of the box. Once I got the layout aligned, drilling was quick and precise. The accuracy is impressive, with clean, straight holes every time, and the included bits worked like a charm. The design is clever, compact, and durable — the aluminum plate feels premium and makes it easy to keep things straight. I love the versatility too; switching between 5mm and 1/4" bits was fast, and the guide holes are clearly labeled. The size is ideal for cabinets, bookcases, and even tighter spaces where a bulky jig wouldn’t fit. For anyone needing quick, repeatable shelf pin drilling, this jig speeds up the use and keeps your project moving fast without compromising quality. If you're doing any custom shelving or cabinet work, this is a must-have tool that saves time and eliminates guesswork.
