really the most difficult thing for a system to do in the bass is a really 'hot' recorded double bass. like the Jeton 100 3315 direct to disc pressing of Moonlight Serenade; track 1, Mondscheinsonata (Round Midnight/Moonlight Serenade), Ray Brown/Laurindo Almeida.
getting the double bass to come alive in your room is a real treat. getting great coherent lively mid-bass is much more relevant to music than deep bass. and if you play this as you continue to improve your system it will tell you how you are doing so far.
the re-issue pressing (a tape was made from the pressing and then a vinyl pressing from that) or digital is not the same. you need the original direct to disc version.
I have both an original and the reissue. No comparison. And yes, I agree with you that this LP is a good way to measure progress in one's system evolution. Those low bass notes in that first cut are tough to get to play cleanly and not distort or overload the room. I am finally getting there after a few years of effort. Ray Brown is finally becoming present in the room with his instrument. I realized I was making progress when I started to hear the texture of the bow on the bass, and not just one low, homogenous mess. This is incredibly nuanced and then the plucking later relative to Almeida's plucking is brilliant. The cool thing for me is that my improvements did not involve any gear changes and very little expense.
Another good one is "This One's for Blanton" on Pablo.
