What works best with Magnepan 1.3 under 3k

After reading a ton of reviews from people that own Magnapans I went out and tried some under 3k preamps. Tried the recommended AR SP16 and Bat 3ix- they sound great- open and clear. Is there anything better under 3k?

cd player- ( deciding on) Ayre cx7e or Bryston BCD1 have old Audio Alchemy
Nordost blue heaven interconnects and wires
B&K ST140 (Looking for a new one)

If CD is your only source consider a new CD player that has variabe tube outs, like the Raysonic 168. I found the outs so good that I sold a $3K preamp
