What Class D amps will drive a 2 ohm load

Just asking.

I see specs into 4 ohms but nothing into difficult speaker loads (like Thiel CS5's).

Thanks for listening, 


I am so pleased that others with, apparently, endless patience and REAL knowledge, have taken the time to contribute positively to this thread.

For me, it doesn’t matter that some of the posts have been made by suppliers / manufacturers. What matters is the quality of information and the clearly stated reasoning behind their position that the right Class D amp, properly designed and built, will drive heavy-load speakers.

There is an obvious point to me: certainly for EU/UK law, products that don’t do what is claimed will very quickly mean suppliers / manufacturers will be brought to book in the context of trading / consumer legislation. Also, most suppliers presumably rely on reputation. If they supplied goods that didn’t do as claimed, that reputation would be damaged pretty quickly.

To those who have contributed constructively, retaining their cool in the face of substantial provocation, I for one appreciate it.

George’s arguments are irrational. For him doubling down power is more important that the absolute power and current the amplifier actually gives.

Sorry but this is wrong, have you ever listened to a pair 25w Mark Levinson ML2’s on a pair of hard to drive speaker like the OP’s? "to a given level" (because they are only 25w after all) they will annihilate any 500w or 1000w Class-D.

This proves that doubling down (current) to below 2ohms into this kind of speaker load is the most important factor for sound quality, not wattage!. ( otherwise we would all own $400 3000W! Behringer NX3000 Class-D’s )

Although if you want to go louder then wattage becomes a factor also, so then the same kind of amp that can double with more watts is needed then.
So you my friend are the irrational one not me.

BTW You’ll never see a pair of ML2’s for sale used as owners die with them!

To which George replied:

George's argument was both incorrect and irrational. This is different from saying that a person is irrational- the principle to use of course is 'attack the argument not the person'. Calling someone else irrational as we see here is a forum violation. In addition, it employed a logical fallacy known as a 'Strawman', since George was trying to say that he had been called irrational when that didn't happen. Logical fallacies are by definition false.

@Dsper — the "doubling thing" we love as audiophiles means that the amp will maintain its output voltage constant despite the drop in load impedance, which in turn means its power supply can adequately provide the increase in current needed to achieve said constant voltage. As you probably remember, volt/ohm= amp which means that every time you halve the ohm, you double the amps, voltage remaining constant. As power (Watts) is the product of volt x amp, it follows that keeping the volt constant means the wattage doubles.
In the real world, however, only a perfect amp will do this and there are no "perfect" amps. Many manufacturers just under specify the 8ohm rating to allow their product to be in spec for the lower loads. Nothing wrong with that in my book, you still need a well-engineered product to achieve numbers close to doubling anyway.
