Low sensitivity is a good thing nowadays, you will be able use your amplifier's full potentional. You quite often can hear complaints, that because of high cd output speakers going loud too early for volume control and then you are offered to buy some special adapters to lower output from cd player.
Actually that's a really good point. It gets loud very quickly with my RS6s, I don't think I get near halfway on the volume control and I have it LOUD.
So may be worth a try after all.
