The S6 Black Edition amplifier is able to meet the needs of the most demanding users, featuring.

To improve the S6 we worked on its strengths and we went even further to achieve higher sound quality.

The circuitry has been revised in the signal path and power management, again surpassing the milestones already achieved in the S6. Power output is now 40W, 15% more than the standard model. The polarisation of the power output valves has been completely revised to eliminate the capacitor and cathode resistor.
The input selection circuit has been implemented using the same technology designed for our most valuable equipment and extreme care has been taken in the design of the ground paths and channel separation. The valuable audio signal, where possible, travels protected in high-quality coaxial cables.
All the new Black Edition series are equipped with 3 digital inputs USB,SPDIF and Toslink.

Nice shelf option
These industrial pipe shelf brackets are a great choice if you’re going for that rustic, farmhouse look. The black iron finish looks clean and modern while still giving off that classic industrial vibe. Once installed, they feel sturdy and well-built. Perfect for holding books, décor, or heavier items when paired with solid wood planks. I like the open design because it really lets whatever you’re displaying stand out. They’re also pretty versatile and work well in different spaces like living rooms, kitchens, or home offices. Just keep in mind that this is the bracket system only, so you’ll need to supply your own wood and possibly some mounting hardware depending on your setup. Overall, they’re a stylish and functional DIY option that adds a lot of character to a space.

Excellent industrial shelving hardware for the price
I bought these as a housewarming-style gift for my brother-in-law, who recently finished building an extension onto his home and finally has the space for a proper office. His family’s aesthetic leans heavily toward that cottage-meets-industrial look, and these brackets fit the brief perfectly. First impressions were excellent. The iron construction feels genuinely heavy-duty, and the machining and threading are better than I expected at this price point. The finish is a clean matte black that looks sharp without feeling overly glossy or cheap. Installation is straightforward if you’re comfortable with basic wall mounting. Because these are iron pipe components, you may find yourself making tiny adjustments with micro shims to get everything perfectly level depending on your wall and stud placement. That’s not a flaw so much as the nature of pipe-style systems. Once dialed in, though, they feel very solid. The scale is also worth mentioning. These are not subtle brackets—they’re a bit of a statement piece. That’s great if you want the shelving to become part of the room’s visual identity, but it’s something to be aware of when planning the space. One thing I actually appreciate is that they don’t include the wood shelves. Bundled wood usually drives up the cost and often isn’t the species or finish you’d want anyway. This way you can choose your own boards and tailor the look to the room—which is exactly what my brother-in-law ended up doing. Overall, a very well-executed industrial shelving system: sturdy, attractive, and surprisingly refined for the price.
