I think Ralph has heard my story before and I agree about impedance matching. Many years ago I had MA-1s driving speakers that were rated at 4 ohms. However, the measured impedance curve dipped below 3 ohms in both the bass and treble range. In many ways those amps sounded wonderful but not with complex or loud music. That is not a criticism of the amps, merely a recommendation to find the right tool to do the job.
As for a multi-channel SS receiver being able to drive the Ascent i, that seems completely irrelevant to driving them with an OTL tube amp in my perspective.
