您好，看了您的回复，我觉得您是这方面的专家。我有一些问题想请教您：
- 你为什么想使用外部独立时钟？
- 你为什么要连接外部线性电源？设备自带的电源不能满足你的需求吗？
- 你自己有线性电源吗？
- 我看到很多帖子都说USB输出的信号时钟可以重置。您认为这种说法正确吗？

I wouldn't say I'm an expert in the area but I do have practical experience
I have tried several streamers and reclockers over the years.
My 4 way active horn system is very dependant on the WAF Najda 3 in / 8 out, DSP XO DAC pre that does the crossovers, time/phase aligning and PEQ correction.
This is currently an older unit with just SPdif input (optical and coax) and native I2S input. It also has a rather good analogue input too.
So to use the Sonore Ultrarendu streamer (I first borrowed and later bought), I had to convert from USB out to SPdif somehow.
Others had recommended the Gustard U18 to do this. I tried the Ultrarendu and Gustard U18 combo and found it to be the best I'd heard so far!
I also tried a I2S over HDMI to native I2S converter and used the i2S over HDMI output on the Gustard U18, but could not find any improvement!
I recently tried a miniDSP Flex 8 XO pre with the similar capabilities as Najda. I found I preferred the sound without the Gustard U18!
Just USB out from the Ultrarendu and straight into the miniDSP Flex 8 USB input.
Ultimately I preferred the sound of the Najda DSP unit over the miniDSP though!
After that I got a Wiim Pro streamer that only does SPdif out. It is capable of bit perfect streaming - just don't use the analogue outputs for anything hifi on the Pro model - it has a very basic DAC!
As with the Ultrarendu, I found an external linear power supply improved the sound quality, better dynamic and sonic cleanness.
I also tried the Wiim Ultra that has USB output for streaming. It has a 230V mains input, so impossible to change the power supply.
I did not find that better than my Ultrarendu or the Wiim Pro in my system! The streamer part is the same as the Pro! The USB output was what I wanted to test..
Back to the Wiim Pro with Linear power and Optical SPdif (optical works best on my system with the Wiim Pro), I have a sound that I really like.
I've also tried 5V 5.8Ah battery power. Prefer the Linear power supply - More get up and go - These things are quite subtle, but there.
I have done blind testing between the Battery power and Linear power on two people and both preferred the linear power!
I am waiting for my Ultrarendu to receive a SW update so I can try Qobuz and Spotify Lossless Connect, rather than the temperamental (for me) DLNA and mConnect app solution.
The connect solutions will not sound better than DLNA of course.
I might try the Topping D10s to do the USB to SPdif convertion as that unit measured extremely well on a Audio Science Review test.
The Wiim Pro streamer with its Qobuz and Spotify lossless functions perform amazingly well.
Very stable streaming connection and easy to use, sounds very good too!

Perhaps not on the S3 Lite as this could be purely a streaming transport. Maybe on the S3 and definitely in the S3 Ultra if that is actually a thing.

Maybe this could be an upgrade path in a similar vein to the way you opened up op-amp rolling?
Offer an improved clock that can be mounted in place of the old one as a user upgrade.
I think this would find many people willing to try.

Update.
I got the Qobuz Connect feature for my Ultrarendu streamer.
I'm also testing a Topping D10s.
Purely as a USB to SPdif converter.
Its Dac is not used.
I compared this back to back Topping against Gustard's U18.
In my system, I prefer the D10s!
It's a more resolved sound.
Even further reduction in perceived distortion, a very calm yet interesting dynamic sound, non fatiguing - just right sounding.
You know when you hear it!
The sound Ultrarendu and D10s achieve beats the Win Pro!
It in the mids and upper frequencies mostly.
I can instantly switch between the two with identical music streams playing and will even do a blind test later to confirm.
Looking forward to seeing how the Fosi S3 streamer sounds.
