i has the ARROs in a prior office system. Like all TOTEMs, they are power hungry speakers …They performed optimally for me with a high current 100 wpc integrated amp. It’s the “grunt” that matters …(amps) to drive them properly.
Best of breed partnering = SIMAUDIO. I ran them with an ARCAM FMJ A32 integrated amp that was close to the SIMAUDIO.
And yes, they were positioned close to the back wall.
