Then there were 2

OK I have 3 amps on my short list but one is not available due to supply chain issues.They are ARC Ref75SE, Rogue Stereo 100, (and not available is Quicksilver Mono KT/120)
Question sin it is down to the Rogue and ARC are the comparable (or as they say a coin flip?) or is one considerably better than the other.
I like the fact that the ARC use KT150 and the bias is accessible on front panel.

The RP-7 should not be used with power amplifiers having an input impedance much below 30k ohms. Into 100k ohms, however, the RP-7 offers a flat, wide-bandwidth response with an upper –3dB frequency of 170kHz" Keep in mind the input impedence of the power amp you will be using with it. I have an RP7 and a Stereo100 and the match is lovely, as it should be with the same brand.

Is that between 2 cabinets or just in 1? Do you have any idea of the efficiency and impedance of the speakers? In a room that size 100-130 watts will work if the speakers are 92dB although you'll be able to run the amps out of gas if you really push it. If the speakers are 4 Ohms you might need more power.
