@ironrick6 , I started with the Node 2 (not the i version) then moved to a Node 2 (N130) with a linear power supply. The improvement is noticeable and I would encourage you to make this move as others have. It is entirely possible that you'll be happy with this combination for a long time.
However, just this week I added a Chord Qutest to the same Node 2 (N130) with the linear power supply. I'm still evaluating the addition of the Qutest and not quite ready to share my thoughts on it.
