There is more to the choice than just the power differential.
There is more to the need for power than just the sensitivity spec.
The sonic difference between these amplifiers, as it relates to ones own preferences as heard driving ones speakers needs be considered.
To me the post by avanti1960 seems most useful. These amps will impose a different sonic character to your speakers. The sound character of each can be somewhat adjusted with tube rolling.
For my 12 x 15' room driving my Tannoy Sterlings having a 91B sensitivity and a fairly flat 8 ohm impedance( not below 5 ohms) I may enjoy the possible additional refinement offered Raven more. Driving my Esoteric MG10s having a sensitivity of 87dB and a 6 ohm impedance (dropping to 3.5 ohms) I might prefer the additional drive offered by the Rogue.
I understand that you have moved to a larger room. Likely larger than my own.
