Hypex DIY Preamplifier Kit Review

[Reddoc]

€770 for the add-on board is a tough sell in today's market, where one can buy for example a WiiM Ultra twice and still have money left.

I really enjoy the Nilai power amps so i am interested in this one- is it for sale anywhere?
Where are you getting the details?
EDIT: Sorry, thanks. just found it at DIYClassD- must be new

Got to agree with you. Hypex is taking the piss surely? I think they are in dreamland if they truly believe that will sell.

It looks to me that Hypex is using these DIY platforms for testing/feedback their flagship products. DIY community is most capable for such tasks, plus these may serve as non-traditional advertisement etc, IF they are really good. If this is the case, such DIY products are win-win for the community. What do you think?

That's one way to see it,one the other hand the full built (with DAC,etc) can also be compared with higher quality full size stuff,like Denafrips Athena,etc.
(I would still go for the Athena + DAC though,I'm a sucker for nice PCBs)

Hi @amirm

Have you considered a follow up test with the available DIY PreDIGin add-on? https://www.diyclassd.com/products/diy-components/accessories/diy-predigin-add-on

If I understand the description correctly, the DSP functionality is limited to a fusion amp setup. With an asking price of € 770, this package doesn't show an obvious added value if you don't have a fusion amp setup.

Has anyone tried to connect a Raspberry Pi inside?

Bad New, it's a DIY preamplifier but can't do anything on the board, the microfit output aren't usable, and input too. I was chatting with Hypex technical service, but hard to find a solution.

Their specs are dodgy.

14dBu is not 4.1Vrms. It's 3.88V RMS
4.1V RMS is 14.5dbu.

4.1V RMS is 14.5dbu.

Not to be too picky, but 14.47dBu, if we're sticking with 2 decimal places.

Yes, works fine. Used RPI 4 board. Of course WiFi is no go inside metal case, but Ethernet cable works as expected. Not sure about the maximum power available to the Pi, tried a RPI 5 with M2 HAT, 1TB M2 disk and had some instability. Possibly that combo draws too much power.

What did you install on the RPI 4 board?
