Then there were 2

Hello,
I was wondering if the Rogue DragoN would work. It’s 300 watts. You will still have the RP7 to produce that awesome sound you like. Also, you might want to try the RP9. It is on another level compared to the RP7. Add the DragoN to that and your done. I am not sure if you are near the Chicagoland area but this dealer is close to me. https://holmaudio.com/This store lets you demo in your home. 

@hshifi You had already suggested the Rogue preamp, I purposely decided on the RP7 as it lets me tailor the sound a bit via tube rolling.
I dislike Class D, never heard one I liked. I don't want SS as I already have one I am keeping (for the time being) This is purely a tube play.

 I am totally in the ARC groove...have seven of their pieces. It's a long strange journey but (not for nothing as they say) I have had my mid-range amp used to power a mastering system playback and it stood up remarkable well against custom Levinson amps.  That's my take on it.

I have the REF 75SE, formerly had the REF 150 nonSE and Classic 120s.  This is the best amp I have had including several solid state before getting into ARC.  My only Rogue experience was the Ares Magnum phonostage.  I was very disappointed in comparison to ARC's phono stages and that would make me expect ARCs amps to better theirs as well.  My speakers are the Wilson Audio Sophia and it drives them very well.  Outside of a poor speaker match I cannot imagine you being disappointed in the 75SE.  Good luck!
