What Class D amps will drive a 2 ohm load

Whatever Ralph.
Seems like this could be the module your using, as you've turned up the force shields a notch higher on this one, if so just go with the buffer by-pass switch. 

I've mentioned before, we're not using anyone's modules.

It seems that what you aren't getting is that comparitors (a kind of chip or circuit used in many class D amps) can be unstable if used with high input impedances. To prevent oscillation, lower impedances are used at their inputs.

Holy crap - 49 amps. Didn't know this one existed

Here's Apollon's version:  https://www.apollonaudio.com/hypex-nc2k-monoblock-amplifier-apollon-audio-nc2kslm/

Yes, 2,000W in 2 ohms. Tell that to some who believe that say a 100W/200W/400W in 8/4/2 ohms amplifier would be more suited to drive 2 ohms speakers just because they double power as impedance halves...

Sorry but what you get is a good PA amp.
Hypex suck in, they purposely put things backwards to confuse at glance. Look again, and that’s peak watts and amps, also the wattage go backwards as the impedance goes down, it gets severly current starved.

Nowhere in this universe can this thing come close to doubling into 2ohms The NC400 of theirs is a far better module as far as current delivery into low impedances it actually goes up in watts instead of down. Data sheet download here

This just gets more interesting.

I emailed, to both Nord and Appollon, the Stereophile measurements for the Thiel CS5's and both suppliers said that their amps would drive them.

For example, Appollon replied that their NC1200SL HYPEX NC1200 BASED AMPLIFIER "...is a perfect choice for your speakers and probably the only class d amplifier that will drive your speakers with ease at 2 ohm loads. The NC1200 module is specially designed for such low impedance loads. Any other class d amplifier will fall apart sound wise with your speakers but the NC1200 shines @ 2 ohms."

So what am I not being told?

Thanks for listening,
