Which Preamp will go well with Mag 3.6R ?

Hello, newbie here...

Pretty much set for speakers and Amp. (Magnepan 3.6R is set.)

1. Amp - Between Bryston 4B SST, or Classe CAM 350 - which amp would YOU choose? (I'm 80% leaning toward Bryston)

2. Should I go with tube or solid for preamp? (I am leaning toward tubes though...) Which preamp will match well with above set?

3. While at it,,, Which CD player do you recommend?

4. Due to limited budget, I am thinking about buying used equipments.
What sould I look for ? or be careful of in buying used equipments?

I've set $5000 budget for CD and preamp

Thanks in advance.
