Best amps for MBL101e's?


I took the plunge and bought 101e's and restarting the upgrade bug. These speakers are not very efficient and in a large room. I have the EMM labs combo, and probably am going to buy the 6010d preamp that I am demoing right now (great phono section, has the ability to match levels for 4 different output channels). My bias in the past has been tubes (MC2000, VT100mkII)...any suggestions?

Thanks,
Chris
