Has anyone compared the 990 to say a krell hts 7.1 or a Meridian 568.2? I know many have compared to lesser equipment but I was wondering how much of a difference there was. The krell costs $8000 but you would be suprised what the dealer cost is and how much they mark up their product. So the build cost is much less than dealer cost. This gets me thinking that the cost of building these are not much higher than the 990 as it seems.
