High Quality USB Interface

This GUSTARD U18 USB digital interface offers a high quality design, ensuring excellent performance and accurate sound reproduction. XU216 from XMOS has 16 cores, which brings rich resources and a smooth experience.

Fully Isolation

Complete grounding isolation is achieved by 200 Mbps isolator to eliminate all interference from your PC.

2nd Generation Clock Synthesizer With Ultra-Low Noise

To generate an extremely accurate clock signal, the U18 uses two Accusilicon AS338 oscillators with a jitter of only 38fs and a Gustard K2 ultra low noise clock synthesizer. Moreover, the power supply of the clocks is done by a LT3045 linear regulator with a noise level of only 0.8µVrms. The power supply stage uses a large custom toroidal transformer, optimized for audio use.

Independent CPLO For Signal Shaping

In the CPLD for signal processing, the isolated IIS signal is reshaped to remove the jitter introduced by the isolator.

Excellent Performance & Wide Compatibility

For its audio outputs, the Gustard U18 offers Toslink Optical, Coaxial, AES and I2S via HDMI. On this last output, it supports high-resolution audio streams up to PCM 32bit 768kHz and DSD512. Moreover, the I2S pinout is configurable in 4 modes to adapt to most devices on the market. Finally, we note the presence of an MCLK input and WCK output on BNC.

No Scent and Gentle
Style: Tolerance Daily Foaming Facial Cleanser
I broke out in a case of Perioral Dermatitis recently and bought this product to help before I could see my doctor. Avene Tolerance facial cleanser has no scent and is very gentle on my skin. It didn’t burn when washing with this product, and even helped to slough off the dead skin around my lips. My face feels clean, not dry. I am still going to see my doc to get an RX for the inflammation, but I do believe this product helped to alleviate the dryness and tightness of my skin and lips. I’ve used other Avene products and I’m very happy with them. Even though these products are more expensive, to me they are well worth the money because they are much more gentle on the skin than any other products I’ve used. I will buy this product again just because of the fact that it’s so gentle. PS: at the time of purchase for this product, I also bought Avene’s Tolerance Control Skin Recovery Cream (you don’t need to use a lot of this one on your entire face), and Avene’s Cicalfate for lips. Between these 3 products, my lips and skin feel a lot better (however, I will still see my doctor because I have Crohn’s Disease and Perioral Dermatitis is considered an extra-intestinal side effect of Crohn’s).

Gentle everyday cleanser!
Style: Tolerance Daily Foaming Facial Cleanser
My go to nightly cleanser! Gentle yet effective. Removes makeup without leaving any residue behind. Also does not dry out my skin or cause breakouts! I would say it’s more of a cream cleanser though. It does not really foam up. It’s a decent size bottle for the price. The pump dispenser is an added plus!

So gentle and moisturizing. Great for super sensitive skin.
Style: Tolerance Daily Foaming Facial Cleanser
This is so gentle and moisturizing. Does not irritate my skin in any way. My skin is super sensitive and I have atopic dermatitis, it has been the best cleanser I’ve used to date. I was using another one from this brand and it was fine but this is the one I will continually stick with from now on. Just hope they don’t change the formula.
