"I'm looking for suggestions of speakers with equivalent or better sound."
That's a really tall order. I honestly don't think you can get what you are asking for in the 9K range.
I think the Wilson Watt Puppy 8 is equal or better sound but they are 28K.
You can probably get 5K for yours taking your budget up to 14K but it's really hard to get the Maggie sound out of similar priced speakers.
Just my 2 cents......
