Direct is always better. Unless something in the chain does something to the sound that you like.
Generally good advice, but in the digital streaming chain there are complications:
1. sometimes an intermediate device isolates noise, for example any time you add a network (ethernet) connection rather than source --. USB --> DAC. This is almost always good.
2. to distribute processing power - both for load balancing and again to isolate the resulting noise. Roon is very clear that they favor a 3-step chain of 1) core, 2) bridge, 3) DAC
That said "downstairs" i go directly from my ROCK core to my DAC. Bad me. Sounds great.
