Amp Recommendations

Hello everyone, posting this for a friend.  He's looking for a new amp.  The current setup is 

Audiolab 6000CDT (Transport)

MSB Link upgraded (DAC)

Conrad Johnson PV-11

Pair of Berning EA-230 (used as monoblocks)

Martin Logan Electromotion

Interconnects are Pangea Audio Premier XL

Choseal Speaker cables (replaced Kimber Kable 4 TC)

The Berning amp just doesn't have enough power to run the ML.  He's looking for  (preferably) a tube amp that is at least 100 wpc.  Also open to an integrated amp (also tubed).  New or used is fine and budget is $3 - 5K.  He started looking and is eyeing PrimaLuna DiaLogue Premium HP,  Almaro A50125A, or VAC PA 100/100.  Thoughts/suggestions.
