Integrated power for KEF R3 Meta

Here is what I have learned from this thread. MC amplifiers are weak and KEF Metas are not a good choice in speakers. Yet a friend of mine in Denver has the KEF R3 Meta (no they are not plastic @audioman58) and he drives them with aplomb with a Simaudio Moon 250i V2  50wpc into 8 ohms class a/b.

My apologies; I interpreted as the KEF Reference series. My opinion was directed solely to the Reference series. The more power KEFs get, the better they sound. 

I agree with Jeffreyw. I have found that without power the reference and the old r series want power.  The bass doesn’t develop without power.

I stand by my statement
