Jadis Orch Ref vs opera consonance m100plus

Main difference for me at this point is

jadis-
rare in Finland, probably very difficult to buy used in finland
certainly over 1200usd used in US meaning 120v meaning i
need a downstep convertor or to modify
probably a better amp than the opera

opera-
can buy used in Finland for under 1200usd
220v and a dealer in my town
made in china
probably worse amp than jadis

also how might these amps rate in comparison:
Audio electronic AE-25
TAD 60
