The Salon 1 has a sensitivity of 87dB/2.83V/m which is moderate voltage demand (not too sensitive, not to hard to drive voltage wise too) @lanjett
It is a current biased speaker though with its impedance dipping below 4 ohm two times at 50Hz and 95Hz. Basically, you need 4-ohm stable amplifier that can deliver decent current flow and moderate VRMS.
Two of this is what you need - Apollon Purifi 1ET9040BA Eigentakt Monoblock
Ample current and power delivery whilst being more efficient and less of heat generators. They have incredible damping factor so control of transducer is TOTL
