I would recommend more power than the minimum required 25w for these speakers. Keep that in mind. Coda S5.5 should be fine but I would probably opt for No.8 V1 just to get more headroom. Not familiar with other amps in your list never heard them. I used to own Pass XA30.8 though and it did drive my Wilson Sabrina ok but it left Class A frequently to deliver more power.
Will an Amp change improve my system ?
My system is WiiM pro ( a great device for $149 !) and a Cambridge CXC V2 CD transport for digital input going into a Schiit Yggdrasil+ DAC going to a Schiit Freya+ preamp into a PS Audio S300 amp into Harbeth 30.2 XD speakers. I am considering replacing the S300 with one of the following: PASS XA-25, Coda S5.5, Benchmark AHB2, or tube Primaluna EVO 400, used Rogers EHF-100 or 200, used Luxman MQ 88uc. I like my current system and wonder if an amp change would improve it significantly ?
