What Class D amps will drive a 2 ohm load

George, no negative comments here, please, but my point I am about to make is very relevant to the discussion, and just another person’s perspective. As most here who know me, I go wayyyyyy back with PWK and his Klipsch Heritage products. I have owned, borrowed, installed for others, and listened to, so many other speakers, and the same goes for power amplification. As much as I enjoy, and own, Heritage, I am certain, part of my enjoyment, comes from the driving amplifiers, simply " coasting along ". You do not hear a speaker, without a driving amp, nor, do you hear an amp, without a driven speaker. It is always, imo, and ime, the combination. Some of us hear an immediate " compression "; some of us hear certain " distortions "; some of us hear a lack of " damping " ( woofer control ), etc. If there are any questions, that reliable measurements cannot tell you, you simply need to try it....On another thread, I recommended to the readers, to read a review of the Peak Consult Dragon Legends, from Mono Stereo, last year, by the same reviewer who just reviewed the Merrill 118s, from Part Time Audiophile. After reading the Merrill review, and realizing I had read the speaker review a year and 1/2 earlier, I needed to read the speaker review, again. Richard Mak, the reviewer, does an excellent job, in both reviews, but, really highlights, greatly, the importance of the speaker / amplifier interaction, and most important, the expectations of the listener. Please read them both. Enjoy ! MrD.

Don't under estimate the Thiel CS5i's, they are truly special.

For about $3k you can get an nCore NC1200 based stereo amplifier from Nord/Apollon that drives 2 ohm speakers with 1200W. Plus your choice of Sparkos or Sonic Imagery discrete opamps to flavor to taste.

IMO this is a huge value.

I don't need that much power and settled on "only" 550W in 2 ohms of the NC500 for my Thiels. That is plenty of power, lowest distortion and non existing hiss and noise.

You guys are just p***ing against the wind quoting big watts, and not quoting the wattage for each halving of impedance at 8, 4, and 2ohms

It’s not about the big watts, Class-D P.A. amps like Crown ect can do that. It’s about the amp being able to come close to doubling it wattage for every halving of impeadance 8, 4, and 2ohms!

The classic massive Mark Levinson ML2 mono blocks at only 25w into 8ohms will sound better into into these speakers than any 10,000w Class-D, because it can double it’s 8ohm wattage all the way down to 1ohm ( 25w 50w 100w 200w). Which means it can "DRIVE" these speakers

Granted it won’t do party levels because after all it’s still only 25w at 8ohms , but it will p**s all over your ice power class-d for sound quality, into these types of speakers.

Cheers George
