Amp for Martin Logan Motion 60XT

Thanks for the responses! I definitely want the headroom to power these speakers and potentially future power hungry speakers. I saw one review of the Motion60s and they used a Sunfire 300 and Silver seven so I think that basically shows higher power is fine. I just don’t understand why the power range hahaI was looking at Parasound A21s previously but I’ve been doing a lot of research on the Hypex class D and they are supposed to be phenomenal. Class D efficiency with class A sound. Read the reviews if you don’t believe me. These are what is used in high end Mola Mola, ATI and NAD amps. The problem with the Crowns and Behringers is that their power is not very clean and they have fans which are a turn off. The NC1200 almost doubles down in 4ohm and 2ohm. The THD plots are impressive.

theres also the Purifi amp which I can find for almost the same price. Same designer who worked for Hypex.

@jnehma1 there are manufacturers like Nord, VTV, and Apollon that build amps with Purifi in them. I like your idea tho, it looks like there are 30day trial periods after ordering. 

@georgehifi Are you speaking from experience on class D or these models in particular, or do you know of test reports you can share that explain what you are talking about?

Thanks everyone. I definitely learned something!
