What Class D amps will drive a 2 ohm load
dsper,All amplifiers running 2 ohms continuously will get hot, independent of class. But I have seen that class D modules (Icepower, hypex, purifi) have current limit to protect the module from overcurrent.As for thermal dissipation, musical signa... 
What Class D amps will drive a 2 ohm load
Rhetorical question: which hypothetical amplifier has more power to drive 2 ohms speakers?Amplifier A:100W at 8 ohms200W at 4 ohms400W at 2 ohmsAmplifier B:400W at 8 ohms700W at 4 ohms550W at 2 ohmsAmplifier A doubles power for each half impedance... 
What Class D amps will drive a 2 ohm load
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 m... 
What Class D amps will drive a 2 ohm load
I am using an Apollon NC800 SL amplifier, based on Hypex nCore NC500, with special buffer using Sparkos SS2590 discrete opamps, to amplify my Thiel CS3.7, which run almost all frequency range near 2 ohms. Recommended, sound great, no background no... 
Balanced preamp recommendation : w4s, hegel, parasound
Maybe a Nord PRE-A preamp to complement the Nord poweramp? https://www.nordacoustics.co.uk/product-page/nord-one-pre-a-pre-amplifer-black  
Help selecting a new preamp
Wyred 4 Sound STP-SE stage 2 is an great sounding solid state preamp. https://wyred4sound.com/products/pre-amps/stp-se  
Why no Class D integrated love? (from manufacturers)
BTW Nord has 2 new lines of integrateds: https://www.nordacoustics.co.uk/int-tvcintegratedamp https://www.nordacoustics.co.uk/nord-one-int-a-integrated-amplifier  
Why no Class D integrated love? (from manufacturers)
I forgot to mention Wyred 4 Sound, although I’m not sure which IcePower modules they use. I hear nothing but good things though.The former STI-500/1000 v1 was based on ICEpower 500ASP/1000ASP.The current STI-500/1000 v2 is based on ICEpower 125ASX... 
Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???
Apollon NC800 stereo or monos, based on nCore NC500 + opamps.https://www.apollonaudio.com/apollon-hypex-nc500-class-d-amplifier-nc800-sl/ 
The Future of Audio Amplification
Maybe that is what the class D amplifiers will be in 10 years more. Class D is evolving really fast. It is the future of audio amplifiers indeed.

Here are measurements of Hypex nCore NC400 DIY kit made with an Audio Precision state of the art, and they are very good looking in the audio band.https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-hypex-nc400-di... 
Peachtree Nova 300
That Stereophile review was a joke... Really poorly tested. 
How does ICEpower 1200AS2 compares to Hypex NC500 implementation?
Personally if I were to choose the 1200AS I definitely would have chosen to use 2 of them, one for each channel, for maximum power reserves (1.200W in 4 ohms is crazy), power supply headroom and channel separation. The boards are not big, so that ... 
How does ICEpower 1200AS2 compares to Hypex NC500 implementation?
NC500 is said to be very transparent and there are several buffer implementations that may add their "house sound": Sonic Imagery and Sparkos both have DIP8 and larger sized opamps, Hattor and Marantz PM10 have their custom buffers, etc. Difficult...
