Does anyone know about ohms on an amp ? I have a Cambridge Audio amp with an 8 ohm capacity but my speakers are Wharfedale 10.1 which have a 6ohm compatibility . I'm confused . They sound ok but looking to get a more powerful set of speakers . Have seen ones with 8ohm on the spec and wanted to know if they would suit my amp better than the ones I have at 6ohms . Any ideas ? thanks
