What amplifier for Magneplanar MG3 for less than ?

I am searching for the right amp to give me excellent staging. I listen mainly to jazz, classical and some popular music at moderate to low volumes. I am currently using a Bryston 4B. I have a YS Audio Symphonies + preamplifier and a YS Audio Concerto line amp. I have an Oracle Premier with a Rega 600 tone arm and a Grado Sonata Reference Cartridge. I also have a Meridian 507 CD player and silver wire interconnects. There are so many amplifiers to chose from and I would like to spend $3K or less.
