@antigrunge2 Exactly, my experience as well. Still, my search is on for the most efficient means to extract maximum sound quality. My present thoughts along this line is server with optical out capability into streamer or streaming dac with optical in capability.
I'd also add complexity vs maximizing simplicity is a trade off. More complexity means more cables, connectors, devices, power supplies, all can generate, be conduits or allow leakage in of EMI/RFI. Greater separation of devices at the same time may theoretically decrease this same noise. I have Trifield Meter and the greatest generation of RFI comes from server/computer motherboards, transformers of all kinds and storage devices such as ssd and hard drives. Put these all under one roof, not good.
Paradoxically, the best solution should be something in between the two extremes. While I'd like to see power supplies, and perhaps storage in separate enclosures, I wouldn't mind seeing optimized usb within servers which may negate need for all kinds of usb thingies, or separate streamers for that fact. They could also offer clean ethernet inputs within servers, devices like Uptone Etherregen wouldn't have to be separate and external. Storage could also be well shielded within server, eliminating the need for NAS or USB external storage. Having the ethernet and usb optimized within a single server also serves to eliminate possible clocking incompatibility, per what you mentioned above.
I do think the Taiko Extreme and Wadax servers address all my requests, minimal devices and maximum sound quality all under one roof. Unfortunately, this comes at prohibitive price for most of us!
