The bass is full but defines in these songs from Diana.
there will be recordings in any audio system that won’t sound like master recordings . For example in the 60s many rock bands just starting out could not afford the best mastering equipment ,or mixing artist. Some may have too much top end, some endemic in Bass. Some mono recordings and older single miked mixes were masterpieces. More then 1/2 recordings out there are far from ideal.
I play music from all different types, which is far more challenging . Even when I owned my Audio store and $100k audio systems not everything sounded like it was being played live in the room ,that would be optimum , but almost impossible
unless you cherry pick the records,and artist.
