Steve, thanks for the info. I may be agreeing with you. I finally got the optical cable that connects the vault to the DAC last night. I did a quick test against my Theta Miles CD player (which I’m hoping to replace with the vault) and the CD player blew away the vault (going through the DAC.) I am using very good audio cables (LAT International). Today I will test the vault directly connected to my amp against the vault going through the DAC. I will also see if there are any adjustments I can make on the DAC to improve things.
As far as the node 2 in my bedroom, it’s working great on WiFi. So I agree with you about the possibility of Wi-Fi being the problem rather than the node 2 for those folks out there not getting good results.
As you suggest, I may end up returning the DAC. I’ll know in the next day or two once I test everything.
