Eversolo Firmware V1.5.60 Adds Spotify Connect Lossless Streaming at 24-bit/44.1 kHz

What makes this step interesting from a technical angle is less the headline spec and more how Eversolo appears to be handling Spotify’s audio pipeline internally. Spotify’s delivery has long been constrained by lossy encoding and fixed gain structures, which often left high-end streamers sounding underutilized. By reworking the internal signal routing and buffering strategy, Eversolo is effectively allowing the Spotify stream to arrive at the DAC stage with fewer intermediate conversions and less aggressive DSP intervention. For listeners familiar with the brand’s house sound, this should translate into more stable imaging and a calmer noise floor, especially on complex material with dense transient information.

There is also a nuanced discussion to be had around the chosen base sample rate. Sticking to a 44.1 kHz clock domain aligns natively with most of Spotify’s catalogue and avoids asynchronous resampling inside the streamer. From an engineering standpoint, this reduces jitter management complexity and keeps the master clock closer to the source format, something many audiophiles prefer over upsampling-heavy approaches. The use of a higher bit-depth container further lowers quantization artefacts during internal processing, even if the musical content itself does not always exploit the full theoretical range.

Compared to other manufacturers that treat Spotify Connect as a convenience feature, Eversolo’s approach suggests a more audiophile-driven prioritization of software architecture. Rather than bolting on higher-quality playback through external apps or proprietary control layers, the familiar Spotify control path is preserved while the hardware backend is refined. This positions Spotify less as a “casual listening” option and more as a viable front end for resolving DACs and analog stages, particularly for users who value integration and signal integrity over platform hopping.
