I would like it if you suggested;
1). Models which are currently in production.
2). Models which do not need to use a 'bass boost' feature in order to reproduce their 'solid bass'
3). Please do not suggest EQ'ing the bass more
Budget is not a concern (well it is, I just want to hear of options at all budget levels).
I like an overall dark sound signature, but very solid, and extended bass is the priority.
Thanks in advance!!
