Older modi 3 and magni heresy issues
Hi, I’m looking for some help troubleshooting a Schiit Modi 3+ and Schiit Magni Heresy stack I bought back in 2022.
When I first got the setup, I had no input sound whatsoever. I did reach out for support at the time and tried troubleshooting with the company, but I ended up moving shortly after and the gear got packed away and kind of forgotten about.
I recently found everything again and decided to go back and fully test it from scratch. Since it’s out of warranty now, I just want to make sure I’m not missing anything obvious before deciding whether it’s worth repairing or replacing.
I’ll be honest, I’m not super experienced with this kind of audio setup, so I’ve just been learning as I go and trying to eliminate variables step by step.
What I’ve tried so far:
Modi 3+ powers on and is detected in Windows
Audio is correctly routed to the Modi
Magni Heresy powers on normally
Tried multiple RCA cables
Confirmed correct routing from Modi line out to Magni input
Tested multiple 6.35mm adapters
Tested with Sennheiser HD58X and IEMs
Tried both gain settings
Volume tested across the full range
USB is in the correct input on the Modi
Result
Still no sound at all from the Magni, no hiss, no crackle, nothing
Additional testing
I also bypassed the entire PC and DAC setup and tested directly using a mobile phone into RCA into the Magni
Same result, completely silent
At this point I am leaning toward a hardware issue with the Magni itself, but I wanted to check with people more experienced with Schiit gear in case I am missing something obvious or there is a known failure mode for this kind of behavior
