what good amplifier match with Speaker Dali 4B ?

Dear Tom,

Thank you, my Dali 4B is 4ohm, about 100W and sensitivity is 91 dB, I am using sansui 607ex, my room is bout 17m2, the sound is not so detail and the bass is not deep, after an period of time using it, I am feeling bored and not satisfy to my taste, now looking more detail sound, more warmer and more deep bass.

Pls advice me what ampli to match my speaker. Thanks

dear,

it is local japaness intergrated amplifier, now i am thinking to get an european/usa intergrated amplifier to replace such as cambridge or NAD or rotel or arcam,... but don't know is that good matching to dali speaker and my taste ? if yes, which brand is better ?

thanks

Thank, i will follow your advice, try to hear more at my friend' house and borrow my friend' ampli to try the speaker and make the dicision to buy later. Thanks again.
