Seth, who started this thread, is a friend of mine and I am sure he appreciates the above information, but I know he is aware of all the above information. I do believe, besides wanting to know of any reviews, he was looking for someone who may own one and/or compared one.
I am surprised we do not hear more on the 6500, the 6900 is still quite new. I heard the 6500 in store a year ago and it sounded nice to me, as much as you can tell on a totally different system than your own and different room. At this price point, the Plinius and others get plently of acknowledgement and I would be curious how the Mac compared, not speculation.
