File transfer from local drives is inferior to TCP/IP transfer on the Olympus when combined with the router.
This is due to a protocol limitation—we cannot modify the local drive protocol to a sufficient degree. However, we can manipulate the TCP/IP data stream to a more meaningful extent.
A NAS acts like a local storage to tcp/ip transfer converter.
The DCD is mentioned because it appears to be a critical component for achieving audiophile-level sound quality with the vast majority of “audiophile” power supplies on the market. If your power supply is of high enough quality, the DCD may not offer an upgrade and can be omitted. That said, I have yet to encounter one that meets that threshold. I would have expected several companies to have incorporated this technology into their designs by now. It seems we are among the most copied companies in the space—but oddly, not in this particular area, despite the fact that it’s not rocket science. Clean power is however more or less a requirement with SFP copper DAC (Direct-Attach) links, which is why we keep mentioning it.
The switch is not mentioned, as it’s not a critical component in achieving this goal—it has no intelligence that affects the data stream.
By the way, this mechanism is why XDMS performs worse than Roon on the Olympus + Router/DCD setup. Bypassing this mechanism would require a significant rewrite of one of XDMS’s core systems. As an alternative, we’ll be offering UPnP support soon. It’s actually ready, but we’re holding off on release to create some breathing room in our current workload, which continues to shift. At the moment, I’m spending most of my time sourcing critical components that went out of stock in many regions after the tariffs were announced.
