S6 Black Edition

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.

Get it
Size: 8 Ounce (Pack of 1), Style: Cool Down Lotion
Love this stuff. Best recovery from the sun I have found. I am very fair and even with sunscreen sometimes still get a little burnt. My friends who get tan and had a long day in the sun are quick to grab this from me and use it at the end of the day. I highly recommend this for anyone. It’s cooling and hydrating. Repair or maintenance for your skin, it’s great for both options. Lightweight and easy to apply. Hands down, worth it!

Smells Great and Works Well
Size: 3 Ounce (Pack of 1), Style: Cool Down Lotion
Smells great and goes on really smoothly. Skin felt soft and refreshed after use. It is pretty "liquidy" and can come out of the bottle a little on the quick and messy side, but nothing too terrible.

Works VERY well, NOT sticky, smells AMAZING!
Size: 16 Ounce (Pack of 1), Style: Cool Down Lotion
So... I had sunburn... very painful across my whole back, top of my forehead & the back of my arms. Stupid, I know... USE SUNBLOCK PEOPLE! However, if u don't because u want "a little color" and end up like me, then I highly recommend this after-sun product. It smells amazing and doesn't leave the sticky residue like green Aloe Vera. After rubbing it in, my hands feel super soft. It gives my skin the hydration it needs so I won't peel (and lose the tan I was desperate for). My personal hack... After the sensitivity of the burn calms, I like keeping a bottle in the fridge for that extra cooling sensation. I love this stuff! Sun Bum is a great product... u should definitely try the sunblock tho, it worked where I applied it! I didn't take a pic for obvious reasons, but when u rub it in, it will dry clear.
