What Class D amps will drive a 2 ohm load

This is a class-D thread. No one is pushing anything. I am stating, quite clearly, that your "push" of EPDR as a relevant value is meaningless w.r.t. Class-D amplifiers. Given that EPDR is meaningless, we don't need to consider 0.9 ohm loading as you have pushed for the Alexia as it has not meaning within a Class-D discussion.  The standard impedance which does not dip below about 2.5-2.6 ohms, is the relevant value for discussion.

BJT has nothing to do with a Class-D discussion, but since you bring up EPDR, EPDR is most damaging to a BJT amplifier in real world conditions because of secondary failure that MOSFETS, and tubes do not experience.

Once again, yes it does sunshine, as you both push the class-d BS, that it can drive the speaker loads were talking about here as the OP ( Thiel CS5) speakers as good as the best BJT amps can

Now if only there were Class-D amplifiers that drove into 2 ohms without any trouble like the op asked ... oh, there are. Cherry Class-D do.  Mytek will as well. There is nothing "sexy" about them, they just do the job they are designed to do. Obviously you have heard them with difficult to drive speakers?

    Just got done talking with Merrill of Merrill Audio.  He says a lot of his customers are trading in their $12K Veritas mono-blocks on his new line of Element amps with GaN FETs.  He said the older GaNs sound better than the newest ones, interesting. 

     I've decided to buy a pair of pre-owned class D Veritas from him at less than half price,   I'm going to pair them with a Levinson 326S preamp, Lumin D2 dac/streamer, Oppo 205, all balanced cables and Magnepan 2.7QR speakers.  

    Merrill  said all of his class D former Veritas and new Element amps are stable down to 1 ohm, George.
   Dsper, a $5K pre-owned pair of Veritas would be an ideal amp solution for any Thiels, Kappas or Apogees you care to use.

Yes, they may be stable that’s only half of the equation, so is a $199 30w NAD 3020 integrated from the 80’s, it’s also "stable" at 2ohm loading, and also on the OP’s Thiel CS5’s, won’t make much music though.

But when I ask him "twice" to produce "true" rms wattage figures (preferably measured by an independent lab) just before clipping at 8, 4, and 2ohms, I was "then" met with a deafening silence.

Only this and also being stable will indicate what’s going with an amp, into serious low impedance’s as the OP’s and many other hi-end speakers have.
