SQ difference - Raspberry Pi vs x86_64?

[Snoopy8]

What have you read? I'm seriously considering it as a next stage for my server.

It's a great deal easier than messing with the clocks 

The Pi5 was designed to boot off microSD, requires a tweak to boot off USB if not using the official power supply, and requires a hat plus further config tweak for NVME. Maybe the issues were people's initial efforts, but I read that some NVME were not compatible ???

I guess it'll have to wait until one of us tries it.

Also, not encouraged by what I have read about issues using a NVME for the OS.

Right, yet in my experience, the only significant improvement is replacing the crystal with ocxo clock. 

Battery power supply, adding power filter hat, vibration isolation, lan cable galvanic isolation, all help.  But none can compare the power of changing the crystal clock.  And 1 +1 is bigger than 2.

Some NVMe drives (mainly WD) are not compatible with most HATs.

Got any good news? 

Thanks for that, though.

2) Pi5 with 10M OCXO clock. 

Where did you get this?

They don't sell Pi 5.  So one have to buy in somewhere else and then send to them to mod.  And I hope they will send to overseas, too.
The original stock Pi 5 is not hot at all, the cooling fan directed controlled by pi5 never turn on when running MPD.   The But the Pi 5 with that 10M clock is a power hunger and it will got to 70-80 degree in several mins (of course it depends on your room temperature).  When Pi 5 at such temperature, it'll become malfunction.  And prolonged high temperature will damage Pi5.  I've got a damaged one from hi temperature (I believe).  So a fan is needed.

This may be relevant @Snoopy8. I've always split the server and client functions, and I know you've mentioned how you think this gives better SQ. The server is a much simpler beast than the client. As far as I can see, it doesn't need replacement clocks and it has so far run totally fine with passive cooling on both the RPi 5 and the NVMe drive. I've yet to check temperatures, but it only draws a maximum of 1.4 amps, and normally averages around 1.1 amps. And, by eliminating the fan, you don't need to worry about that source of noise, powering it independently, etc.

@hkphantomgtr I'll need to put the page through Google Translate, but it looks very interesting. I'm going to have to tackle the clock issue with my client build when I get to it.

I think, even a pi5 is just a client, I believe it still deserves a better clock.

I'm agreeing with you.

Thanks for that, though.

In recent days testing, I found that the sound quality varies with the source of power (of course)..... guess what?

Powered my pi 5 set solely by battery is the worse scenario.  It lost the most in density, the dynamic, and the focus.  It really took me by surprise.

The other 2 contesters are 1) powering by LPS directly to the filter hat, and 2) powering by LPS to the battery hat (including compulsory and automatic battery charging).  I think the result is needless to say.  The difference in sound is even more obvious.  Yet the sound of 1) is a bit strange to my ears.  I need to find out the problem and solution, e.g. detaching the battery hat, relocating the speakers.  I'm afraid I only can do this not earlier than this Sunday.

And powering the battery hat by 5V LPS and 12V LPS with same DC cables also make the difference.  5V wins quite clearly.

I know a few people who say battery power leads to disappointing SQ. I always use a Linear Power Supply of some sort. I've been scared off of batteries!
