Back in the early eighties, I tested the first mono amplifier that was being developed by Bang & Olufsen on the Infinity RS 1b in Greenland. Quarterly prices are expensive up in the high north, therefore the small room. I apologize for the blossoms on the speakers, it’s a wife thing lol. But back to the test of the first mono amplifier from the same company that lives on Ps audio. They were 150 watts in 4 ohms and one of the sets I’ve been most impoverished has been able to pull my 1ber and that with a fantasy sound. I look forward to testing the M700 on the same set of speakers as many years later.
