My impression of the BS line of streamers has always been ICON > Nano > Node X (or ES A6) > the older Node 130 or 132, based on the descriptive statements provided by Tarun about the sound of BS. There are also a handful of feedback reports and reviews stating that the older Nodes are beaten by the Wiim Ultra. That was why I never bothered to consider BS until the Nano and ICON arrived. Now your mention that the old Node (with an LPS mod) and the Nano (with LPS) sound alike kind of surprises me.
Anyway, my proposed upgrade path is purely based on the aforementioned notion. If I were the OP, I would not be content with achieving only about 60% of the target sound performance. If not the Nano, there must be some other higher-end yet still affordable streamer alternative that could get you there with the help of a capable DDC—perhaps the ICON or Rivo+.
Maybe I’ll try the U26 myself and see how much it can elevate my system. This curiosity really drives me nuts sometimes.
