@cleeds I have owned Auralic Aries G1 and Lumin U1 Mini. Currently I am using a network renderer in my DAC (Bricasti M3) as a Roon endpoint (Roon core duties are handled by Mac Mini) without an outboard dedicated streamer. I also occasionally use MConnect to bypass Roon and stream direct from streaming services (Qobuz and Tidal).
The M3 has two toroidal transformers running digital and analog sections of the unit. There’s nothing ti fiddle with and I don’t have any plans to do so. The point I was trying to make is it all depends on the design and implementation. There are excellent streamers that utilize buffering and equally good sounding units that leverage caching.
Here’s the M3 with its hood popped (this isn’t my unit, pic from hifi news).
