The change was not subtle in my system and really exposed how running roon on my iMac or using the Vega’s built in streamer was not providing the performance you can get when things are implemented on a dedicated system. The music is much more detailed and has significantly more weight to it. I am very pleased with the change.
Congratulations on your very successful outcome. I am glad that you discovered for your self that it is not a simplistic case of "it's only about the 1s and zeros" as was mentioned early in this thread. The quality of the digital source (Streamer/server/transport) most definitely matter as does DAC quality. As has wisely been said before, it all matters if you want to achieve excellent sound quality.
