Singxer SDA-6 Pro 2 is the latest flagship DAC developed with AKM’s new-generation AK4191+dual AK4499EX DAC chips and a custom-developed FPGA signal processing architecture. Singxer has optimized the internals of the SDA-6 Pro 2 to achieve class-leading performance promising quality output with ultra-low distortion and high SNR performance. The SDA6 Pro 2 supports native DSD and 32-bit PCM audio signals!!

New-Generation AKM DAC Chipset:-

Enjoy amazing sound signal decoding performance with a rich, velvety AKM in-house sound. The Singxer SDA6 Pro 2 comes equipped with a new-gen AK4191+Dual AK4499EX DAC chipset. This dual DAC arrangement delivers quality output by providing a natural tone, exquisite details, ultra-clear background, and low distortion performance. The output has amazing dynamics and high SNR performance.

Upgraded XMOS USB Processor Chipset:-

Singxer has upgraded the USB processor chip on the SDA6 Pro 2. It now comes with an XMOS XU316 16-core 3rd generation processor that enables smooth sound signal processing supporting up to 32-bit/76kHz PCM and native DSD512 audio signals. The SDA 6 Pro 2 is a true flagship-level performer in terms of USB Processing and overall performance.

Specially Developed Large-Scale FPGA Architecture:-

In order to achieve smooth digital audio signal processing, SDA-6 Pro 2 features a specially optimized FPGA architecture. It adopts self-developed third-gen algorithms with original multi-input channel isolation technology to ensure the purity of each input mode. Singxer SDA-6 Pro 2 features a high-performance digital-analog hybrid Phase-Locked Loop, that provides excellent clock synchronization recovery technology. It significantly improves the performance by filtering external digital input jitter secondary PLL.

Self-Developed Low-Jitter Clock Architecture:-

Singxer SDA-6 Pro 2 features a self-developed adaptive clock system technology. The DAC has a built-in 4-way independent ultra-low jitter crystal that is configured using a femtosecond clock system for the USB part. The clock architecture is embedded with Singxer’s self-developed thermostat technology to maintain a constant temperature. The SDA-6 Pro 2 also supports external 10M clock input for the USB interface while the other interfaces use WCK input.

Consistent Performance With Premium Power Supply:-

Singxer has a built-in 40-watt customized O-type transformer. The output of the four independent power supply winds up to 20 groups of distributed voltage regulator lines. Both the digital and the analog sections get a proper supply of power ensuring consistent performance in any given scenario. 

Here is the test data for the production version of the SDA-6 PRO, based on the APX555: -

These are very pretty. The perfect size for any age ear. Really girly. They don't hurt the ears and they are not too heavy. Nice and light.

These little butterfly Earrings are the perfect touch of personality for your ears. I got these for a friend's birthday and she's worn them every day since. When I picked these up, they were advertised as sterling silver which was a necessity for her ears. She hasnt had any issues and she hasn't had to take them out at all. The clasps are your average butterfly backing. And she did note that the back came off during sleep one night but it could be she is a hard sleeper. Other than that, they are secure. They are larger studs. Not awful large or gaudy. But people have noticed and complimented on them. They add that perfect touch of whimsy without exclaiming give me attention. Perfect to dress up or down and birthstones match anything after all!

Cute little butterflies!
Color: 10.Oct(Pink Tourmaline), Color: 10.Oct(Pink Tourmaline)
I got these for my daughter who just recently got her ears pierced for the first time. Since she is so young, I decided to try them first to see how well they handle. First, I was very impressed that they included plastic and metal backs. There’s also a nice little baggie to put the earrings in when they’re not in use. Second, my ears are very sensitive, which was a concern with wearing these, but after a few hours, they seemed to be fine still. Usually, after a few hours, I have to take earrings out. I could have worn these for longer and been OK. Last they are super cute! They match the description and color perfectly! I was very impressed. I could definitely see myself buying another pair. The earrings were also very good size not too big and not too small. Perfect for adult or child.

These really are so cute--the purple color of the butterfly really stands out and when I'm wearing them, I can't even tell that I have them on.

Perfect. A must have!
Size: XX-Large, Color: Nude
Perfect fit! After 2 battles with breast cancer and breast reconstruction I find it very difficult to find strapless or any bra for that matter that fit and are comfortable … this bra not only fits it stays put! I have purchased some pricey ones in the past but this gives a lot of bang for your buck. I also love the fact it stays in place- has rubber like adhesive that sticks to your skin and has no wires. I feel mangled after basically being amputated by a double mastectomy- I worry about the bra falling down exposing the fact I have no “nips” because cancer took all that away from me. Additionally, I like that it comes with removable straps for adjustability for extra support if needed. The quality seems to be good but I have yet to wash, just like any bra - gentle cycle wash and a flat air dry will extend the life of the bra.
