Rogue pharaoh II or Cronus Magnum III ?

@lradder ,

Will you elaborate as to your opinion to avoid ribbon tweeters with the Pharaoh 2?

This is a Solid State, Class D Amp at 250 watts - 8 ohms / 400 watts - 4 ohms. it produces strong highs. I should have stated if you like bright highs, matching the Pharaoh 2 with ribbon tweeters will be bright. Just be careful if you are sensitive to brightness.

Yes, but a tube preamp section.

Wouldn't that alleviate that brightness?

To a large part, yes. However there are many articles you can google to see how power tubes and Solid State Amps control the "tone" of an amp's output.

@thecarpathian it all boils down to synergy between the components in the chain. I have a Pharaoh II and it sounds awesome with my Sf Olympica  Novo I with a silk dome tweeter. If I install my GoldenEar BRX with a Ribbon tweeter it is a bit on the bright side, not awful but brighter.

Need to match your components, and no matter what the amp is I will never own a Beryllium tweeter period.
