Does anybody have Singxer f-1 firmware of any revision?
I recently overwrite the f-1 firmware with that of SU-1 so that it does not work.
Please send me the firmware to revive my f-1.

I was looking at the thread beginning, and at that moment you could find different X208 XMOS converters, and if I am not wrong there was only one version with galvanic isolation from the first stage, and into the output SPDIF stage, and that was the F1 version.
Now I made a search and only Singxer seems to be only one offering the F1, at a very high price. Is that so?
People stopped experimenting with this USB to I2S converter, connecting it to a DAC?
Maybe because more and more DACs are including the X208 stage internally? My Topping D50 has one, and many others. do.
Is that the way to go now?
The other people offering X208 stages, with and without isolation, was DIYINHK, and it seems few people are buying that from them.
World's lowest noise 1.0uV regulator from Analog Devices or 0.8uV from Linear Technology
New DXIO PRO3Z uses the latest XMOS XCORE-200 XU216-512, it is equal to Two XU208 in One chip.

Uptone Audio ISO REGEN
"The UpTone Audio ISO REGEN is the first device—designed specifically for quality music systems—to deliver both true high-speed galvanic isolation and extremely high signal integrity in a single, small and affordable package."
May 25, 2021: We are sorry to report that the very popular ISO REGEN (nearly 2,000 units sold) must now be discontinued. This is because the Silanna ICE09USB galvanic isolation chip was discontinued by the manufacturer two years ago and all stocks are gone. UpTone is developing several new USB products. One will be an improved USB REGEN (think ISO REGEN but without galvanic isolation yet with some enhancements) in same case size and similar price. The other two new USB products are VERY radical and advanced designs (drawing on some of EtherREGEN's tech), but those will be larger and at higher price points (similar to EtherREGEN price). Please STAY TUNED!
Fortunately, I found a less expensive solution, when I understood the problem was the Noise injected by the PC onto the USB power lines, I first looked for a USB "data-only" cable, but I couldn't find one, so I found the next best thing:
For me, I solved my USB noise problem by using the ifi iDefender+ to "disconnect" the USB Power lines. It interrupts the USB power, and allows injection of "clean" 5V power if your downstream DAC needs USB power to function.
All the "USB Noise" is gone when I put the USB A-A ifi iDefender+ in-line with my Topping D90 !!
Note, that each DAC we connect to the same noisy source will also need a USB Power line interrupter, like the Ifi iDefender+ and if your device needs USB power I found the ifi iPower+ is very quiet - I tried it with my USB powered SWL radios and they were silent - noisy PSU's make those radios unusable while charging.

Any XMOS variation with DC power to pair with Dave? Need Toslink out. So some different brands have better clocks? Will this increase performance off toslink? Thanks.
