Can you give an example? This is new to me (been an "audiophile" for 35 yearsSimply avoid dangerous songs. I hope that they are not available in the music services.

Cool. Was genuinely curious. Won't play it though
So why do tracks like that exist?
I guess due to something wrong in production stage...So why do tracks like that exist?
Thanks Obi-wan !0.25 mV in idle, 1.2 mV for full scale 1 kHz sine.
And I got above 1 V DC for songs which are known for DC content. So no DC offset protection.
So, why dont they use dc coupling capacitors on the analog output of the WiiM Ultra? Maybe for a couple of reasons.I'm curious to knowing the purposes to have a full DC coupled audio amplifier, maybe they don't trust on capacitors? Are marketing purposes or even a response cut at one or two hertz it's too much and hurts the ears?
Yes, thats good advice: - inside a rca contact with a physically smaller cap, or split the rca cables in the middle with a little box containing one capacitor in series with + per channel.I was referring to input of power amplifier. I can't se any operating reason to not already insert a capacitor like you posted.
Static DC offset on output of any good op amp are generally low and not a problem. DC offsets from bad digital mastering, can be more harmful and any power amp inputs should consider this.
Maybe it's just a philosophical thinking but I see more logic and safe, to put the decoupling on power amp inputs.
Anyway, the suggested capacitor, can be mounted on a cable itself, without voiding warranty.
It's not too uncommon to design electronics in such a way that each device has to protect itself from DC, if required. DC protected input, directly coupled output.You will need some DC protection at the output of the source, or at the input of the power amp.
I have measured the DC offset on my Hypex ncore at the amplifiers loudspeaker output terminal with Ultra connected , it was only 2 mV so theres no worryI use a Ncore amp without any issues. Haven't meassured though.
