Pass Labs XA25 paired with Marten Oscar Duo

Hi everybody,

i got pass labs XA25 (25wats class a) running Marten OScar Duo ( 86db 6ohms ). My question is about the power needed for the speakers. If anyone has experience with similar combo let me know what will i get with pass labs x250.5 ( my dealer has an used to offer for listening). really like the A class sound but sometimes seems i miss a little bit of power. Sometimes its crazy good :)

Thanks,

B
