Deep, powerful, impactful, detailed, dynamic, fast, smooth and natural bass that sounds like music heard live is like the solid foundation of a well built house.
OR.....Like:
The 'ooh' in the 'ooh la la' and the 'ooh mow mow',
the 'wow' in the 'bow chicka bow wow',
the 'yaya' in the 'gitchi yaya dadda',
the 'it' in 'Let it be',
the 'bang' in 'bang a gong',
the 'shama lama' in the 'shama lama ding dong'
And the 'rhythm' in the 'get the rhythm, get the rhythm, there you go, there you effin go'.
All this and I'm not even a bass-head, more like a high quality bass appreciator.
