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.

They taste better than expected- make sure to check the label
Color: Assorted, Size: 6 Ounce (Pack of 1)
The company is going through a transition right now, so some of them have xylitol and some of them do not. If you are looking for the kind with xylitol, this one is not it. But it makes it very confusing because one page will have different products and someone will have xylitol and someone will not so make sure you are looking at the ingredients and cross referencing what you can see in the picture and what's in the description. I got a couple kinds and I have found that what is in the picture the ingredients in the picture is what I actually got. If you're looking for the Non- xylitol kind with the other two ingredients that are good for teeth than it's this this one. I use other xylitol products so I was looking for the other two ingredients specifically. If either way it doesn't matter to you then I would go ahead and purchase for an adult or a child. But you have to be more careful with the xylitol kind if you were using other types of xylitol or have a sensitive stomach or IBS or you're giving it to a child. It may upset a child's stomach, especially if eaten in high amounts, you can get gas and diarrhea. So I was looking for specifically the one without xylitol. And for a product without xylitol or sugar, these taste great. I am a fan however I do like the.zolli balz kind a bit better. For a younger child, this shape is less of a chocking hazard.

Tastes good, but I sounded like a deflating pool raft for about 3-5 hours after consumption
Color: Natural Fruit Variety, Size: 25 Count (Pack of 1)
Listen. I bought these because they’re “good for your teeth,” “won’t spike blood sugar,” and apparently dentists recommend them. Cute. Adorable. I love the idea of a guilt-free lollipop. What I was not prepared for was the industrial-strength intestinal chaos that followed. These things taste great — like, dangerously great. I ate two. Not a whole bag. Not half a bag. Just two little sugar-free angel pops. And about an hour later I realized I had made a tactical miscalculation. My stomach started sounding like someone was inflating a pool raft inside me using a faulty air compressor. I was walking around my house like a Victorian woman with “nerves,” clutching my abdomen and praying for mercy. The gas? Oh, the gas. I don’t know what mystical sugar alcohol is in these, but it turned my digestive system into a wind farm. I produced enough air to power a small suburban neighborhood. I scared the cat. I scared myself. At one point I swear my own fart ricocheted off the hardwood floor and came back for a second round. Do they hurt your teeth? No! Do they spike your blood sugar? Absolutely not. Do they destroy your social life for 12–24 hours? Yes. With precision. If you want a great-tasting candy that won’t mess with your glucose — and you live alone, outdoors, or somewhere with excellent ventilation — go for it. Five stars for flavor. One star for the fact that these turned me into a human whoopee cushion. Final verdict: delicious but dangerous. Approach with caution… and maybe open a window.

These are amazing
Color: Natural Fruit Variety, Size: 25 Count (Pack of 1), Color: Natural Fruit Variety, Size: 25 Count (Pack of 1)
Recently diagnosed diabetic with a huge sweet tooth... I was looking everywhere for something to feed the craving without putting me into medical danger. Not only are these delicious but they are better than most regular lollis. I immediately went to purchase other zolli candy. 10/10 will repurchase and recommend

YUMMY & non gas causing (less sorbitol)
For a sugar free pop - it’s yummy and not overloaded with that gas-causing chemical ‘sorbitol’ Perfect for smoke cessation, or nighttime pie hole stuffing problems
