Thank you for helping clarify
@restorer-john.
Maybe I was naive, but I did some simple calculations based on listening distance, sensitivity etc and figured that even 10 watts would be ‘enough’ to at least drive them to a moderate level.. and that therefore the Cambridge should be up to the job. The low sensitivity of the speakers/low wattage makes it unfeasable in this case?
Would things look different if the amp also had a, lets say, 50 watt rating into 4 ohm? Or would the low 25w@8 ohm still cause problems?
