Help me decide my next amp

Hello Gents,
Currently I own pair of Sonus Faber sonetto 2 speakers driven by pathos classic one mk3. Everything is fine but sometimes I feel like I need more power (lack of authority and grunt). Currently I'm looking at several amps.

• NAD 275 BEE  + NAD 165BEE
• Marantz PM 17-MK II + SM17
  
• Primare i30
• NCore hypex NC400 x 2 Monoblocks
• Quad 606 + Quad 66 pre amp

 All of the amps/preamps are pre owned and every combination is within the range of 1000-1200e.
 What would be your choice?

Thanks
