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.

Great product for south Florida resident.
I LOVE this sunscreen so much! I have tried so many different sunscreens and they always leave me greasy and shiny in a few hours time. I live in south Florida and I know the importance of protecting my skin especially my face against the harsh sunlight. This sunscreen feels light and mousterizes my skin without leaving it greasy and oily. The light cucumber scent is absoluteltly lovely but in no way overpowering. It goes great under my makeup and doesn't have the sunscreen heavy feeling that I despise. It's a little pricey but I do plan on buying again when I run out. P.S my boyfriend also occasionally uses this moisturizer and he also enjoys it and says it feels like great quality stuff.

Organic face lotion and sunscreen in ONE!
I had been looking all over for an organic face lotion and sunscreen and was having a hard time. I tried several that left a white residue on my face and then I found this one. It has a nice, light, relatively thin consistently that absorbs very easily, without any residue or caking. I have tried both the unscented and the cucumber and I like both. I find the cucumber scent refreshing and not overwhelming- although I know others didn't like it. I think the 1.7 oz last about 3-4 months, which was awesome! And it is small enough to travel with on a plane! This is a fantastic product! I only wish it didn't cost so much!

Love it!
I absolutely love this moisturizer! I originally got a sample of it through Birchbox and fell in love. It is the first facial moisturizer I've used that doesn't cause face demons and it actually got rid of my dry flaky bits around mouth and nose area after just a few uses. It smells delightful and fresh, it's very lightweight, and it's not at all greasy or oily feeling. I wanted to purchase it immediately after sampling but Birchbox was selling this same size bottle for $35 and I couldn't justify that so when Amazon had it listed for $15 at the time, I snatched it up! I will definitely be repurchasing this product again and again and again!

great product, horrid shipping packaging
Very moisturizing yet very light. I love the smell of cucumber, too. And the best feature is that it's organic, so you can safely use it on a daily basis. While I love the product, I do not like the way they ship it. When I received my COOLA, the box was smashed. But I did not imagine that it damaged the tube as well. You can kind of see them on the photo, but it created sharp-edged creases, from where it often starts leaking. I did not want to take a chance, so I contacted the seller, and they sent me a replacement. But the replacement box was also smashed, although the tube itself was not damaged this time. If you want to buy products as gifts, you can never buy them from this seller. COOLA itself is fantastic, so I wanted to give a 5 star, but the way they carelessly ship is unacceptable, which would have resulted in 2 stars, but they promptly replaced it, so I'd give 3.5, but for lack of 0.5 increment, I gave it 4 stars.

LOVES LOVES LOVES
This is the absolute best sunscreen on the market for your face. Or at least that I've ever tried. Being in my 20's I'm getting pretty obsessed with preventative care, and face sunscreen every day is a big priority. I actually received a sample size in my Birch Box Monthly Subscription and I fell in love with it. So happy I found a cheaper once on Amazon because it usually is about $35! The smell is NOTHING like a sunscreen, it smells like fresh cucumber, and the texture is not thick. I put it on under my makeup and it does not feel the slightest bit heavy. Needless to say, unless one day I have an allergic reaction to it, I will be using this sunscreen until I die.
