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.
For a serious workout and demo of deep bass i always put on “Deeper Well”
from Emmylou Harris’s live Spyboy album. Building intensity of bass guitar and
drums ( played by great musicians) is just phenomenal. If your system can handle it Regretfully not issued on vinyl yet.
Does the 10" vinyl of tony allen/jeff mills convey as well as the digital? I'm almost vinyl-only and I love both artists!
As an aside (in techno territory which often is not actually deep bass heavy) it could be worth listening to some of the Dean Decosta tracks from late 90/ early 00 on Mosaic etc. Minimal but with nice bass weight....
