RFI emissions would be conducted, not radiated, at music-playback frequencies. 'Radiated' RFI goes from 30MHz to 1GHz.So -how is digital damaging itself ? Wouldn't the 'conducted' energy harm other audio components instead ?

"RFI emissions would be conducted, not radiated, at music-playback frequencies. 'Radiated' RFI goes from 30MHz to 1GHz."
The components in the circuitry act like "capacitors" at those frequencies.... That's how the RFI just permeates the circuit.
The airborne RFI can be demonstrated by holding an AM radio near an active digital playback circuit..... Or especially near an active computer.
"So -how is digital damaging itself ? Wouldn't the 'conducted' energy harm other audio components instead ?"
Yes, in fact.... I've seen this demonstrated..... A vinyl rig sounds a lot better with no active digital circuitry connected to the system than with active digital circuitry connected to the system. The problem with digital playback is that the RFI is an integral part of the process.
I personally think prior to the digital age, it was much easier to get good sound quality with seemingly modest gear.
Radiated RFI comes from power supplies, motors, transformers, heaters, lamps.Do we know what digital-chipsets radiate at ? The clock could be doing it...
