Much depends upon your speaker choice. Efficient speakers can get by with less power and thus can typically require fewer dollars spent on amplification.
That said, you can get into expensive tube amps, etc with highly efficient speakers.
Many think choosing the speaker for you should then drive the amp search. That was my path. My 3.6 Maggies truly opened up with a pair of substantial moni block amps.
There is no secret formula or magic bean, just your ears, wallet, research and an open mind about the sound you seek.
Good luck in your search!!
