Music streamers from $5,000 to $10,000 are purpose-built digital sources where every stage of the signal chain is optimized independently. Custom power supplies feed separate digital and analog boards. DAC implementations use flagship-tier conversion with proprietary filtering. Network interfaces are electrically isolated from the audio circuitry. At this level, the streamer isn't the weak link in any system, period. The differences between Qobuz masters and Spotify compressed become instantly, almost uncomfortably, obvious. You'll find yourself re-evaluating your entire library.
