What the signal looks like by the time it reaches your DAC — and where the damage, if any, actually happens.
Where the stream lives and where it can slip
A digital stream is a sequence of numbers. Between the server and your DAC those numbers travel through routers, buffers and software renderers, and at any point they can either arrive intact or not. The meaningful question is where errors genuinely occur — and where they demonstrably don't.
Network transmission itself is robust. TCP/IP includes error-checking and retransmission; a corrupted packet is resent, not guessed at. By the time audio data lands in your streaming device's buffer, the bits are, in the overwhelming majority of domestic setups, identical to the source file. This is verifiable: rip a CD, stream the same master of that album from a lossless service, and a null test — subtracting one from the other — returns silence, provided the two are the same edition and properly time-aligned. The bits matched.
Where things genuinely diverge is format and processing. A lossy stream (AAC at 256 kbps, Ogg Vorbis, MP3) has already discarded data the encoder judged inaudible; that decision is permanent and upstream of everything you own. A lossless stream — FLAC or ALAC at CD resolution or above — carries all the original data. The distinction is real and measurable. What the numbers describe, what is audible, and what is marketing is a longer conversation, but the format choice is the one that actually matters here.
The second live variable is the software renderer. Some players apply replay-gain normalisation, EQ, or sample-rate conversion without advertising the fact. Check your app's settings: anything in the signal path between the file and the DAC output is a potential departure from bit-perfect delivery. Most dedicated streaming apps aimed at hi-fi listeners offer a "direct" or "lossless" mode precisely to disable that processing.
Clock jitter — timing irregularity in the digital signal — is real but handled inside the DAC's receiver circuitry. A well-designed DAC reclocks the incoming stream regardless of source quality. Worry about format first, processing second, and jitter last.
