You are correct Charles, when I bought the ascendo I did think that if I liked the speakers they would require a new amp, even though I really like the Moore amp. I did buy a 100w/ch hybrid; the 300B was much better. So for 9 months the 300B has been in place. I'd say that on 50% of the recordings the ascendo are fully engaged, on 30% I can hear the bass and lower mid need more, but overall it still sound good; & on a 20% it is very clear that more amp is needed. So for now, I enjoy what I have while considering another amp.
I have found that ratings and published specs can only be used as guidelines, you never know until you hook it up and have a good listen. In this case a powerful 13w seems better to me than a 100w hybrid and my 30w push pull. But if anyone asked me about the Ascendo, I'd say a very good 20w in a smaller room would be the minimum.
