Nautilus 805 and signature 805 tweeter

My experience with the "regular" nautilus 805 was that its top end could be a tad metalic/hard. True, it could be something else in the playback chain but could a few people tell me if the tweeter on the sig805 could occasionally have this problem too or was it a much better tweeter? I ask this because though the 805 could sometimes show this symptom there were qualities about this speaker that i did like.
