Power/Current: How much is realistic?

Was considering Pass x600.8 or x260.8 Would i ever use that power with these panels. Would there be a difference in sound or just a waste of power.
Thanks

That should work just fine.

I was always under the impression that it’s not really possible to overdrive speakers that require high current to drive like the Martin Logan’s or Dynaudio’s - at least that’s what I have been told over the years.
While you probably would not use the excess power, I was of the understanding that it imparts a greater ease to the sound because of the high reserves available. Perhaps @atmasphere can correct that if untrue.
I was a Krell user up to the FPB cx era and am now a Pass Labs X 0.8 user. The sound is pretty different so if you really like the bass slam that Krell gives you you won’t find it with the Pass Labs. You probably won’t even find it with current D’Agostino’s.

Thanks for your input .Now i just want to research options for class D 
Ok do not crucify me. I did some research on it here and i get dizzy with it
Any comments or just stay with what i know..

This is in need of correction- you can overdrive any speaker if you have enough power!

I would certainly give them a try. Class D is different from regular solid state- its artifacts are not the same. There can be difficulties with low impedances on account of the output filter of the amplifier; you'll have to check with the manufacturer on that. But the low impedance at high frequencies may not be much of an issue as there is not nearly as much power up high.
