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.

FITS WELL, LENGTH IS GREAT, FEEL IS COMFORTABLE, REASONABLY COOL...MOISTURE WICKING TYPE OF FABRIC
Ok. So I got a job in a retail sort of warehouse and they require collar shirts. So to believe it or not I have struggled to find a shirt that is comfortable, looks decent, fits well, and is not that hot. I bought some Reebok cotton knit shirts and they were too hot, I have to tailor them because they were too long when they arrived and don't fit my body well. I mean the fabric does lay on your body well.
I bought some inexpensive polo shirts that are polyester. The polyester is soft finish. So I wound up keeping them to wear.
Then I tried some Red Kapp work shirts. The shirts fit well but were too long, and even after tailoring them to length they didn't feel good and didn't feel flexible.
So at last I had a polyester university shirt that I like the fit and length and isn't that hot. So I happened to google polyester slim fit polo and came across Amazon Essentials Standard Slim-Fit polo.
These shirts are just what I have been looking for. The polyester finish is not really soft or rough but smooth. Kind of like a golf shirt. The length and fit were PERFECT when they arrived. AMAZON HIT THE HOME RUN on these shirts.
For reference, I am a whopping 5' 2". My frame is small. Even a lot of "small" shirts fit large. My frame is small but kind of full, if that makes any sense.
So all in all I am 100% pleased with these shirts and I am going to put them to use right away.
I might even buy some extra one's to wear on a hot day or something. They are just plain polos but have a decent look to them if you wanted to use them for regular wear.

Good budget golf shirt.
I was skeptical to purchase this shirt as it seemed a bit underpriced but I decided to give it a try and was not disappointed. It is very lightweight which is perfect for those warm golf outings. The material does not scratch and is breathable and the quality of the shirt seems great for the low price. I've only worn it a few times but so far I am impressed As for the fit, this fit me very well and I am usually very picky about how shirts fit me. I'd give this a try before buying a more expensive golf shirt, especially for the beginner.

Decent fit, good quality, great value
I'm 6' 4" tall (1.93m), but very thin, so I bought a Small, which is the size I wear for almost all men's short-sleeve shirts (tees, polos, and button-downs). The fit of this shirt is surprisingly roomy, although I'm not complaining given the price point. The shoulders and body could be a just tiny bit more tailored, especially given the easy drape and movement of this pique knit polyester fabric, which hangs where it wants to and glides effortlessly against the skin. I could never, ever feel constrained or constricted in this shirt. I almost wish the fabric were a tiny bit stiffer. The length is slightly generous, but not excessive. The collar lies down properly (no curling at the corners, no unwanted creases), although this is usually the case with synthetic fabric polos. Despite the minor flaws with this shirt, I like the overall appearance, value, and quality, and I plan to buy several more in different colors.

A shockingly good polo shirt!
OK. Amazon Brand. How good can it be? Well, shame on me. I bought one as "cheap" knock around polo shirts for the beach However, what I received was actually a very nice quality polo shirt with a great fit. (Large, "Trim fit" fits me well....average build, 5'9", 155 lbs, 32 waist). While I can appreciate nice clothes, I am only as fashion conscious as the average 58 year old male. With that caveat, I would unquestionably wear this golfing, at summer party or at a causal restaurant . The material has a nice feel, dries quickly and looks like it will resist snagging, though that it a risk with any polyester shirt. I cannot yet speak about long term durability, but I will no doubt recover my $15 investment. I have since ordered 5 shirts more because I lost weight and needed new shirts. Is this shirt as nice at the $90 ones my wife buys me at a "high end", unnamed "preppy" shop? No, not quite. But awfully close!

Buy this shirt!
You need to buy this shirt! I bought one for a golf outing and like it so much I went back and bought all the colors that were available. At $15, these are a superb value and look great.
Fit: this is an athletic / slim fit shirt. I am 5’9” and 160 lbs and a Medium fits me perfectly. Fits much better than Banana Republic polos. The collar sits nicely, the button placement is correct (not too high not too low). The cuffs do not have a band so they don’t ride up.
Fabric: 100% polyester so you can wash it and stick it right in the dryer and it comes out with no wrinkles. NOTE: I had trouble ironing this shirt. Best bet is toss it in the dryer for a few minutes to get wrinkles out. The colors I have are vibrant and there is a slight texture but not as much as a pique.
