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,

Nord Acoustics base most of their amps on Hypex and are entirely happy to state those amps will be able to drive speakers at 2ohms.  Independent testing has pros and cons and, having perused several hi-fi forums for some years, I've long since concluded the only "proof" is to demo and listen with your own kit and ears.

Coincidentally, I have the joy of a demo with a pre-amp in 5 days and, assuming the SQ makes me smile, I will need to partner it with a power amp.  A Nord One MP NC252 (entry level) is going to get a run, as is a Mytek Brooklyn Amp (NAD's own C 268 will also be given a whirl as it's there).  All are class D and a friend of mine, with decent ears for detail, rates the Mytek highly.  Just for transparency, my current speakers don't engage the 2ohms issue but future speakers may so that's something I keep in mind.

If the NORD comes close to the Mytek, it will give me the best part of GBP £1,000 for another piece of kit :-) .  In that event, I will exercise great self-control and (probably) not smile smugly at my friend....

@dsper Hope you find what you need / want.
A few minutes ago (14:00ish hrs GMT), I spoke with Colin at Nord Acoustics primarily with my own system in mind.

However, I remembered this thread and mentioned it to him. Colin is positive that even Nord's entry level "MP" amps will, in almost all cases, be able to drive speakers at 2ohms.  I'd say to the OP, contact Nord directly and run your thoughts by them.  I'm pretty sure the last thing Colin will want to do is sell an amp that turns out to be useless!

It's disappointing that this thread descended into an echo of 99% of cable threads....

PS:  For the avoidance of doubt, I have zero vested interest in any audio equipment manufacturer or supplier.
Now your twisting things by saying "useless".
Of course it will "work" and he will say so, but will it get the very best out of the speakers?, DEFINITELY NOT! especially in the bass where they are a pig of a load.

George, once again you post with a hostility that is uncalled for. There was nothing "twisted" about what I said. It was fair use of English language. The provocative language you use does not reflect well on you or your credibility. If you are so sure of the view you state, why don’t you let Nord (and others) know they are wrong? That’s a rhetorical question.
George, I appreciate that you responded with a more constructive post. I’m not going to get further involved as, for me, hi-fi is about the music more than the equipment although the latter isn’t without interest. I also don’t pretend to have the level of knowledge evidently demonstrated by numerous contributors to these forums.

As for the vexed issue of speaker loads and compatible amps, my kit (now and potential) is unlikely to engage that conundrum in the foreseeable future, although, part of my curiosity wishes I was able to arrange a real world listen to a heavy-load speaker pair with a quality Class D amp :-). Sadly, I’m not in a position to do so!

For context, my own system is relatively lowly and even if a demo goes well later this week (a distinctly non-classic NAD C 658 - hence my own interest in adding a power amp), the new kit will hardly be mentioned in the same breath as much of the equipment discussed within the forums.

In any case, I sincerely wish everyone happy listening and/or hi-fi hobbying.

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.

K (definitely not a seller of hi-fi equipment)
