Hi PaulW, I’ve finished the tests for now. I want to make it clear that I don’t mean to alarm anyone, I just wanted to share this. I’ve been battling network noise for a long time, and I immediately hear a difference when something isn’t right or has changed. So, with a direct connection to the Wi-Fi router (i.e., without a repeater or Wi-Fi bridge), and with the NA network cleanup still in series, I can again detect a clear difference in sound. Various smartphones, tablets, and laptops all sound different when controlled via Wi-Fi. It’s always Squeeze/Squeeze. I’m always playing my WAV files from the internal SSD (K50). The sound of the music either becomes more spacious and wider, or it becomes more closed, narrower, and therefore more present. When controlled with the Samsung tablet, the music sounds a bit brighter and remains more closed in its musical presentation. The distance between the tablet and the K50 is 4 meters. But I always diligently switch to airplane mode. Whether airplane mode is on or off, the difference in sound is very marginal. The difference in sound remains marginal even when all devices are active on the Wi-Fi network, i.e., not in airplane mode. So I can confirm that the sound differences remain the same regardless of whether a direct connection to the router or my Wi-Fi bridge is active. The sound becomes interesting again when my Wi-Fi bridge with the 7m ViaBlue cable and the NA Origin power supply is reconnected. Immediately, the music becomes more harmonious and open, and the sibilance almost completely disappears – it doesn’t sound digital at all. However, the differences depending on which device is in control still persist.
