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.

Lightweight and soft
Color: Navy Blue Seersucker, Size: King(108"x90")
I purchased this as someone who is constantly waking up too hot with blankets, but too cold without. This comforter has been a game changer. I’m getting much better sleep, and while I still wake up a little too warm sometimes, it’s significantly less than I was previously.

ightweight Cooling Comforter That Actually Feels Good for Hot Nights
This seersucker cooling comforter has been a nice upgrade for warmer nights. It’s very lightweight and breathable, so it doesn’t feel heavy or trapping heat like a traditional comforter. The fabric has a soft, slightly silky feel, and the seersucker texture gives it a bit of airflow that helps it stay more comfortable. The fit is good on a Twin size bed with enough drape over the sides without feeling oversized or bulky. It lays nicely on the bed and doesn’t bunch up easily, which makes it easy to straighten out in the morning. Thickness-wise, it’s on the thinner side, which is actually what makes it work for hot sleepers. It’s not meant to be a heavy blanket and more of a light, breathable layer that still feels like a comforter. The reversible design is a nice touch too depending on which side you prefer. Overall, it’s easy to use, lightweight, and comfortable for summer or warm sleepers. It feels like good value if you want something simple that helps cut down on overheating without overcomplicating things.

Cooling Blanket for Hot Sleepers, Soft Lightweight Comfort with a Cool-to-the-Touch Feel
This reversible cooling blanket is a great option for anyone who sleeps warm. It’s incredibly soft, very lightweight, and has that instantly cool-to-the-touch feel that makes it especially comfortable for hot sleepers. What I liked most is how airy and breathable it feels without being heavy or stuffy. It’s comfortable enough to use all night and gives that nice cooling sensation when you first pull it over you. The softness also makes it feel cozy without sacrificing the lightweight design. My only real wish is that it came with a matching pillowcase, because that would make it feel even more complete as a sleep set. Pros: Extremely soft and comfortable Cool to the touch Lightweight and airy feel Great for hot sleepers Breathable without feeling heavy Cons: Does not include a matching pillowcase Verdict: If you tend to sleep hot, this is a really nice lightweight cooling blanket. It’s soft, breathable, and comfortable with a refreshing cool feel. I just wish it included a pillowcase to make the set feel complete

Cooling Blanket is a sleep saver for me!
This is the second product I have used from bedsmile and as with the other one, this is a great product! It truly is a cooling blanket. I am a very hot sleeper and live in a hot, humid climate, so this has been a sleep saver for me! One side is silky smooth and feels so good on your skin. The other side has a texture to it which is great if you want to use it as your only bedding, which I do. It covers well and hangs over the edges as it should. I ordered the white one and it is bright and unblemished. The silky side magically feels much cooler than typical bedding and keeps me cooler during the night. It is lightweight but heavy enough to make you feel that you are "under the covers". In my opinion, putting additional covers over it would defeat the purpose but if you live in a cooler climate, it would still be beneficial to use this blanket as the silky coolness would help get a good night's sleep anywhere. Another great benefit of this product is that it does not have any strange odors when unpacking. I did wash it before using, but honestly, I am not sure it was necessary.
