High frequency noise from the tweeters? Sounds like a low end receiver? Well, I'm glad you found a pre/pro you like now in the Aragon but those comments do a real dis-service to the unit I am listening to.

I've demo'd a lot of equipment and the 990 is equal to some of the lowest noise floors I've heard. This is vs. B&K, Arcam, Myryad and Citation. It's close enough in sound quality to these to be closer to a matter of personal preference than glaring flaws to determine the decision IMO. I've also listened 'middle to high end' receivers: Denon 3803 and Pio 45TX (although no H/K admittedly), and it's certainly an improvement in sound quality from these.

I'm also not an Outlaw fanboy. I've demo'd their equipment twice before this and returned it. First the 950, then the 7100. Well priced units but I felt justified in paying a little more for something I liked better in both cases. I was pleasantly surprized by the 990 though and will likely be keeping it.

Maybe you have a defective unit, setup problems or just don't find the 990's sound to your liking. But, any more extreme hyperbole and I think it's time to call shenanigans!
