Rogue pharaoh II or Cronus Magnum III ?

Two different animals. The Magnum has a tube power amp and the Pharaoh has a class D solid state. Any of them should be fine with the L100 speakers. BTW, my friend uses the Rogue tube separates with 85db sensitive Harbeths and it sounds damn good!

I use a 200wpc integrated amp with my JBL L100 Classic speakers and also a single SVS sub. In my room, the JBL speakers do not give enough oomph in the bass and the sub takes care of it.  The room is approximately 800 square feet. I do not play the music loud but on occasion when I do, all I can say is wow. 

The Cronus Magnum has one of the most likeable sounds out of any amplifier on the market.  

The Pharaoh does not. 

Magnum sounds good but the build quality is suspect. 

JBL definitely not audiophile class speakers. LOL get rid of those things.
