Mbl 101e mkii best amplifiers

I am driving them with 2 pairs of Parasound JC5 bridged, one pair for each speaker.  They sound magnificent IMO; even better than I heard at the shows with MBL monoblocks.
No brightness whatsoever, which some people complain about at the shows.
Just pure, sweet, airy highs, gorgeous, full midrange, and rock-solid bass.
Holographic, wall-to-wall soundstage. 
The J5s produce about 1200 W into 8 ohms each in bridged mode, way more than MBL amps. That means 2400 W into 8 ohms per speaker!
You might do slightly better with 4 JC+ monoblocks but for about double the price of the JC5s.  
I also got very good results with the older Rotel RMB1095s--used 2 of those in bridged mode. Very powerful sound but is not quite as refined as the Parasound JCs.

Best,

I spent 8 lovely hours listening to them in a purpose built room - Musical Fidelity AMS-100 amp…. wow ;-)

I regret not buying an AMS-50 at that time.

Sadly MF no longer produce either… 

Those need HUGE amounts of power.  If you are not going to run MBL amps, I would recommend the AVM MA 8.3 monos.  They are 1100w into all loads and will handle those speakers well while also not being bright and are quite comfortable with the 4 ohm demand of those speakers.
