    Bass worse after 3 hours

    alfa100, If the prominent bass effect remains constant after many hours, and this has been the attribute of the amplifiers since new, it may just be the characteristic of the amplifier after it warms up. Other people have related the strong bass of the Point 8 series over the Point 5 series...
