Mini Monitors under $500 used


I have a small room 10x10x8 that Im using as a den. Have a Nad 326bee and Marantz 6250 cd, what would you recommend for speakers? Detail, sound stage, and resolution are important to me.
thank you for answering

After searching through all the mini monitors, I purchased the Silverline Minuet Supremes. For my surround sound minis bought the Monitor Audio 90s. A real sleeper that was purchased for $60 for the pair,new in the box.
Larger monitor bagains include the Quad 12L, Quad 11L, VS VR1, Usher 520 and Wharfedale 10.2.
ACI Sapphire III or Anniversary if you can find a good deal. I thought my old Sonus Faber Concertinos sounded good but the Sapphire III were much better.
Right now the Airmotiv monitors are on sale. You can get the Airmotiv4 or Airmotiv5 for under $500 and they have built-in biamplification. This is a high-tech composite slot-loaded woofer with a Heil-type folded ribbon tweeter.

There is also a pair of Quad 11 L2's on A-gon for $450/pair. I have no affiliation with the sale or seller. Those little Quads are fabulous and relentlessly engaging. Beautifully made, too.
