I’ve been using a Sprout100 as a dac for over 2years, sound fantastic. And I upgraded to a Chord Quest and use the Sprout as a volume control, sound even better.
Recently I bought a beyerdynamic A20 headphone amp to pair with my DT880/600ohm, as the A20 has a rca pass through, and the rca output dosen’t defeat even when headphones were plugged, so I chain the components like this, I thought I can just mute the sprout when I using the A20.
After connecting all components and turn on the power, I heard several loud crackle sound, and the Sprout never turn on again.
Have I done something wrong? Or just bad luck?
