What Class D amps will drive a 2 ohm load

Wow!
The Wilson Alexia's get into areas of the Kappa 9's for difficult to drive?
Did not know that, thought all Wilson's were very efficient speakers.

We're gonna need a bigger boat...

I’ve had Thiels for 12 years but have since moved onto to Magnepan 20.7’s. The best amp I ever found for my Thiel 2.7s was the Pass X series and a Pass x150.8 would probably work but an x250.8 would be better. As far as "digital" amps goe, if you poke around the Thiel users groups you’ll find that ALOT and I do mean ALOT of Thiel owners were using Bel Canto digital amps most often the Ref 1000 to drive them. I tried those amps with my own speakers and they worked really really well for my classical and jazz listening but not quite so well as the Pass products.

I said pages back the "better" Class-D’s like the BC Ref-1000 will work, and probably to the owner sound fine with the op’s Thiel CS-5’s.
But "he" hasn’t heard the CS5’s at their best yet until he’s heard an amp that can do <2ohms without breaking a sweat far better, like the Pass X150.8, then he’ll know that Class-D was doing it hard.

Yes efficient 90db like many Wilson’s, but a right b***h of a load like most them also, EPDR (impedance + phase angle) down to 0.9ohm!!! in the bass.
OTL’s will drive them, and pigs might fly!! What was that Supertramp track? oh yes "Dreamer"

Having read this very interesting discussion in its entirety several times I have to ask the commentators a question since neither the pros or cons truly answered the original Inquiry. 
Let's say I want to take a plunge into class D but do not want to revamp my entire system  and  the speakers in user are rated at 90db efficiency with nominal impedance of 8 ohms 3ohms minimum.  Can a class D amplifier (let's use 300w per channel)do justice and get the best or close to the best from the speakers? 
Let's hear your opinions.
