Amp for Martin Logan Motion 60XT


I seemed to be digging into a dark hole about recommended speaker wattage. I’m not sure how much amplification I should strive for to power the Motion 60XT’s. ML recommends 40-400watts for these. Is that in 4ohms? If I got an amp that could do 700watts in 4ohms would I damage the speakers? I am interested in either Hypex or Purifi amp. Not sure between NC400, NC500, NC1200, or Purifi. Any recommendations?
Thanks,

@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.

I’ve been doing a lot of research on the Hypex class D and they are supposed to be phenomenal.

You need to understand how they behave into 2ohms, when you do they become far from phenomenal.

@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?

Yes, that’s why you need to study "independent tests" closer like Stereophile’s into 2ohm loading, and if they don’t have it you know why, they can’t handle it, complain or blow fuses.
Class-D’s do well doubling wattage from 8ohm to 4ohm. But they **** themselves trying to double wattage from 4ohm to 2ohms, sometimes even going backwards
Good BJT linear amps will do this, like the ones I posted about.
That why I posted this to you https://forum.audiogon.com/posts/1942037
If it were correct that all you need is big wattage we’d all own $429 Behringer 3000w amps
I’m not saying Class-D won’t work and sound ok into your speakers, it probably will and sound ok to you, till you hear a linear amp some day that can do 2ohms it without breaking a sweat, then you’ll understand.
