I appreciate your fair, neutral, and realistic assessment. I'd like to comment on music type as a factor in the "worth it" decision. When I upgraded from the Jot w/ internal DAC to Jot + Bimby, the improvement was significant and immediately noticeable when listening to Jazz, vocals, soft rock, or music with mostly acoustic instruments, quiet passages, and a higher dynamic range. By improvements, I'm referring mostly to increased sound stage width and separation between instruments. When listening to synthesized or electronic music such as EDM and some new age tracks, or hard rock with electric guitars and few quiet passages, the improvement and the "worth it" factor was substantially lower and in many cases, imperceptible. So for me, the type of music I plan to play through my rig the majority of the time would be a significant consideration.
