I have listened to the Arros with Musical Fidelity, Naim and Rega integrated amp and CD combinations, and thought the amps sounded best top to bottom in the order listed. For some reason, in a medium sized room the MF A5 and A3.5 sounded fantastic with the Arros. Since your room is fairly small, you could probably get away with the 50 watt Nait 5i or the MF X-T100 amp, either of which should be capable of driving the Arros and you to complete satisfaction.
Also, since the Rogue and Jolidas seem to work well, I wonder how the Primaluna Prologue II would sound with the Arros? I like this amp in combination with other speakers, but have not heard it with any Totems.
