Neglected to mention three dedicated streamers I've used, therefore, streamers without server capability. These commonly called two computer setups. Which leads me to emphasize rendering or port optimization and integration with dacs. Best ports on streamers and dacs can vary greatly, one needs to match streamer to dac here. For instance far too many servers are less than optimal with usb implementation, rendering of the usb is critical for max performance, and very likely plays role in my preference for Roon vs Stylus proprietary player via new streamer. The JCAT usb card with it's optimal rendering could upset the scale. Another streamer I came close to purchasing, the Antipodes K50 claims AES/EBU is optimal port, and other streamers may prefer I2S, one must do the research with both streamer and dac in order to discover optimal compatibility.
Also, it wasn't my intention to rate music players, I only have direct experience with Roon, Audirvana, Foobar, HQPlayer, and now Stylus, I have no idea what is preferable for someone else and their setups. My only intent is to state I'm getting sublime SQ with my present Roon setup, perhaps Stylus will outperform in time. I can understand the logic for why it should, and for why any proprietary player could do same.
