yea but you probably never ran a CM4 especially on M.2 memory (PCI-E).
I reckon a good CM4 install (they do run stable at 2Ghz) is considerably better than any RPi5, and using a good board, makes the pi5 look not such a great deal after all.
Follow Ups:
...they do run stable at 2Ghz
with the RPi3 / DigiOne used in the garage system. As a music player, there's simply no need for Cray supercomputer power. Media library lives on a Synology NAS for shared access for all the players around the manse.
To reduce power consumption, heat and noise, I declock mine to 800 mHz (leaving memory running at half that) and power using a 1A battery. ultraRendu used upstairs also requires only 1A.
Me too. My pc is running at 480 mHz and doing upsampling to 192k

Great that you bring it up.
I've been running a CM4 attached to a Waveshare IO-Base in my "main" system
for quite some time. And I've been using a 2230 NVME SSD. Since about 6 months
a 2TB! 2230 SSD. (BTW: different types of SSDs were causing different sound signatures). I tried all other storage options (SD,eMMC,USB-SATA) against it!
With above setup I've been using my IMO (still) excellent Allo Katana HAT DAC.
Why?? USB is rather crappy on these Waveshare IO boards.
The system ran @2200MHz. At times I was running even @2300MHz. All with passive
cooling of course.
And this setup had been my best RPI audio streaming and playback setup for quite some time!
And. I also own all other types of RPis. Just to mention it.
Bottom line.
Here you have it. Black on white. This CM4 setup was/is "in audiophile terms" considerably worse compared to my new RPi5 setup. The RPi5 is simply a lot
better in many areas. Just have a look at the specs for a start.
Keep in mind though. Not just the HW matters. Poorly integrated SW can cause
a lot of trouble. Since the RPi5 is a rather new device, there might be space for improvement on the SW side for most of the people out there.
As usual. How one judges or values the achieved changes is a pretty subjective
matter with a lot of variables at play...
Enjoy.
Note:
We're a small group of audiophiles over here running pretty similar setups. The opinions or - most of the time - experiences I am expressing over here are usually verified against several other systems and ears out there.
