Turn,
Given the low hours I've logged with the Mentor 5's, I'm not in a position to begin making statements with any kind of authority. I'll have a better story to tell once I've cooked em in and have tried em on a slew of electronics and room configurations. That said, my understanding is that the Mentor series represents a significant step beyond the popular and very affordable Ikon. Of course, anyone would expect as much when you climb up the food chain. As for the high end; I wouldn't refer to the Mentor 5 as bright. At this point, what I'm getting is a upper mid-range/treble that speaks very clearly and coherently, projecting well into the space. It's forward, but not bright. In fact, its a bit more polite than my Totem's - making less than stellar recordings quite enjoyable. Now, back to the break-in process!
