Remember in the Matrix how the operators could visualize the scene by watching green symbols raining down the computer screen? Apparently, Jason doesn’t need to listen to the music, he watches a graph of the music. A $300 bluetooth amp should generate some great looking charts for you.
I still laugh at how we were all caught up in amplifier specs in the late 70s/early 80s. % THD and power output seemed so important. Then one day I heard a good amp without negative feedback which is how they got such great looking specs. The lesson is measurements are a tool for the designer. How it sounds is for the listener.
