Spotify’s long-awaited Lossless tier is here, but early testing suggests it isn’t truly “bit-perfect” on Windows yet. In a detailed experiment, the YouTube channel The Headphone Show compared a verified FLAC track played through Tidal, Qobuz, and Spotify’s lossless option. Using an APx555B Series Audio Analyzer, a Holo Audio Red DAC, and DeltaWave to check for exact parity, Tidal and Qobuz delivered bit-perfect playback. Spotify’s output didn’t precisely match the original file.
The catch likely isn’t pure codec quality so much as the Windows audio pipeline. On Windows, Spotify currently runs in shared mode, which means audio travels through the operating system’s mixer before reaching your DAC. That shared path can introduce resampling or subtle changes that break bit-perfect integrity. Competing services offer direct output to the DAC via exclusive modes, bypassing the Windows mixer and preserving the original signal.
There is good news for listeners who care about absolute fidelity. A Spotify community manager has said that WASAPI Exclusive Mode support is in development. Exclusive Mode would let Spotify send audio straight to your DAC, enabling genuine bit-perfect playback on Windows. There’s no ETA, but it’s actively being worked on.
Until official support arrives, power users are turning to third-party tools as a workaround. Utilities such as FlexASIO and VB-CABLE Virtual Audio Device can help route audio more directly and minimize the operating system’s influence. These solutions require a bit of setup but can serve as a temporary bridge for audiophiles.
What this means for you:
– If you want guaranteed bit-perfect playback on Windows right now, services that support exclusive output modes hold an edge.
– Spotify’s Lossless can still sound excellent for most listeners, but perfectionists may notice that it’s not identical to the original file in current Windows builds.
– Watch for Spotify to roll out WASAPI Exclusive Mode; it should close the gap once available.
– Advanced users can experiment with FlexASIO or VB-CABLE as a stop-gap, and ensure Windows sound enhancements are disabled while matching your device’s sample rate to the source material.
Bottom line: Spotify Lossless is a major step forward, but on Windows, true “lossless” depends on bypassing the system mixer. With Exclusive Mode on the roadmap and viable interim workarounds, bit-perfect Spotify playback looks less like a promise and more like a near-future reality.
