To me, after decades with high current solid state amplification, appreciated slam… which tends to be much greater in solid state. The midrange tends to be a tad leaner and the bass transients really fast… this gives the characteristic slap of fast bass. But, I have never heard this in live performance… amplified or acoustical. High quality tubed amplification tends to have a more fully fleshed out midrange and upper bass and the bass is finely nuanced… but the transient rise is slower… which is actually what I hear in live venues.
We either drink the same water or hang out at the same live un-amplified music venues.😊. This has been my observation for many years listening to acoustic double bass and cello. All acoustic instruments in actuality when heard in a natural environment.
