Thanks everybody. It looks like the winner at this point is....DC 13.4! I have to say, I too find the active noise attenuating very strange, though I'm sure people get used to it. I quite like a bit of background noise to reassure me all is well with the engine. On another tack, has anyone used the Stop Gap spectacle cushions that DC advertise as an accessory, and do they make a real difference if one wears glasses?
