Integrated amp and low sensitivity speakers

Hello,

I am looking for a used integrated amp that has the ability to handle speakers with low sensitivity. Budget is 700.00 to 1000.00.

I have owned several amps but nothing has really grabbed me:

Onkyo a9555 - Was just ok for me, nothing special
Outlaw – Build quality issue
Bryston b60 - Just not enough power, Not enough bass
Sansui au 717 –Was just ok for me, nothing special

I have researched:

Rega - Mira-Bro
Creek 5330
Unison
Plinius 8100 (Looks good on paper)

My concern is the amps listed above just do not have enough power our current and would limit my choice for speakers.
