There are really good youtube videos showing all the "ins and outs" of the RME. I found after about an hour watching those going through the steps with the RME sitting on my desk I think I have it all figured out. Not too bad at all.
Move on from my Bryston BDA-1?
Given the advancement in DAC technology would I achieve a noticeable (started to say significant) improvement in audible performance by upgrading from my current (but early generation) Bryston BDA-1? I am hesitate on the assumption that the internals of the Bryston (e.g., power supplies, output stage) are still hi-grade but understand the CS-4398 chips have been surpassed. I should mention in the system I stream from a Bluesound Node 2i (and in another use an identical streamer with a Topping D90 DAC).
