Improve Raspberry 4 streamer

[officialsm]

Hi,
i'm using a 4 GB ram Raspberry 4 with Moode Audio for streaming. Output throught USB to CXA81 integrated dac amplifier.
Raspberry is assembled with a custom enclosure, oled display and power on/off management board (as picture below taken during works).

I would like to improve performance, if possible. How can i do? Thinking add some reclocker or dac board or somwthing else?

I think USB output is the best solution.

Control temperature (in the box without fan any fan?).

Don't waste money on reclocker...

Hi, with room 21-22° C the RAsp cpu temperature is around 55-58° C

Even when the box is closed?

Of course.

Yes just use the USB output, should be fine.
I'd prefer a heatsink myself if there's any chance Moode starts doing cpu intensive stuff, scanning your library for example.

Do you think something like IFI PURIFIER added on usb could helps?

 

[simbloke]

I'm pretty sure Amir has reviewed a few things like that and the answer was no. My searching is failing to find it...

Nope, Nope, and Nope. Just purchase a DAC that is shown to properly sanitize it's inputs. The Pi4 USB is correctly implemented to spec.

Thank you. Could you suggests kind of dac doing that well?

Check out Amir's measurement section. As I don't know your format needs, feature needs, budget etc but your CXA81 is a Cambridge product and they seem to have a solid engineering approach.

I would just stick with that...

Plenty of, starting @100$.

Search SMSL, Topping etc...

Use USB.

I'm using Topping E30 DAC usb connected to Pi4 and it sounds great. Topping connected to Cambridge integrated Amplifier.

I would investigate digital room correction (or headphone EQ) with CamillaDSP.

I am using a Topping D10s on my main listening system with a Pi 4 running PiCorePlayer. It sounds fine. I also have a headphone only setup with a Topping D50s/A50s. All of them using the Pi's USB.

I am using too a RPI 4 running PiCorePlayer with Topping D10s feeding SPIDF AES into my Genelec 8340 active speakers. So far, I am pretty happy with the outcome especially considering what I spent in comparison to 4-5 times more expensive streamers.

How is the SPDIF to AES conversion done?

I just brought a SPIDF AES cable like this one https://www.thomann.de/de/pro_snake...B8IbHoy_r5FMBb52HYSU5dYDYSF2AbdIaAu5QEALw_wcB.

if the cable run is shorter I assume less than 15 meters, then you do not need a 75 - 110 ohm impedance transformer. Mine is just 3 meters and hence I am not using any transformer. but if you need one, they are not expensive and should cost less than 50 bucks.

Can I ask what you mean by improve performance? In keeping with the objectivist bent of ASR, it may be hard to make any improvements that you will discern as audibly better. But there may be ways to improve its SINAD (THD+N) rating that may still be something you want to achieve. I for one do not discount the value of increased self satisfaction of knowing your gear can achieve the cleanest signal possible. For me it is akin to tweaking my Porsche to incrementally improve its zero to 60 mph time although that will have no perceptible impact on how quickly I get to work each day (purely hypothetical analogy though, since I drive a Prius).
