Power amp/integrated amp suggestions for SUPER POWER HUNGRY/INEFFICIENT SPEAKERS

These are the speakers

As you can read: suggested power rating of 100-300w, 87dB sensitivity. I’m gonna need a brute of an amp to drive these things.

I have this headphone amp, which can be used as a preamp for powered desktop speakers, but don’t know if it could be used as a preamp for a power amp.

Any and all thoughts appreciated.

Edit: looks like the Lyr 2 can be used as a preamp. So that leaves me with the decision of the power amp.

(B) Without prejudice to (A) above....Everything in this hobby is built to its pricepoint = you only get what you pay for. Hence, at your stated pricepoint strata, there is negligible to nil audio performance differentiation between them all. Your choice is distilled down to just "pick one of ’em" from the available pool of contenders and pretenders . (C) on a more positive note.... IMO you are forced to go for used if you want to step up to at least mid-fi eqyipent . I'd suggest looking at a used NAD C370 integrated amp at that Pricepoint strata. Best of luck.
