The older Genesis speakers (up to around 2005) had impedances that went down sometimes to 1 ohm, so while they don't require much power, 60W is plenty, we generally recommend far larger SS amp. The Genesis I60 was designed for these punishing loads, and while we sold out long ago, they sometimes come up in the used section here.
I've heard the ECI3 with the G501 which matched pretty well as long as you're not cranking it.
