Pre-amp for Manley MonoBlock 160W

I've just bought a pair of Manley Monoblock 160W to drive dynaudio 1.3 and is wondering which tube(or ss?) preamp is a good match?

If you are bold enough to listen to what your source sounds like, go passive it will color the siginal the least. The manley amps are beefy and should be able to give you the signal needed unless your source has a very low output.
give a listen to the joule electra and if you can find one, an ARC SP-10.
good luck
I use a Cat with my VTL 300's. I'm on my 3rd CAT. I also have A BAT 5i which worked well. It has a thinner and leaner sound. The quickness some people prefer.You will need adapters, the BAT is balanced.
