Bookshelves for McIntosh ma6300 Integrated?

Taking the plunge and buying a McIntosh before the retail goes up. Have a good deal for 2,500k new. Want to bundle some bookshelves for further negotiations. Can you recommend the best pairing of my new 6300 with the following brands: Definitive Audio, Monitor Audio, Vienna Accoustic, Sonus Faber. 2k is my max for the bookshelves.

Thanks ahead of time.
