Mytek slams Hypex in Stereophile Amp Review
Mytek's chief designer, Michal Jurewicz, told me. "Hypex [class-D modules] cannot drive it, the amps collapse, but this Brooklyn Amp does it with ease."

Which is pretty interesting, because the closest I could find to their specs is from ICEpower modules. :)
I've not been able to do comparisons with Hypex vs. ICEpower amps, so I have no idea what this is about. I use both but certainly not with difficult speakers.

All these class D companies utilize modules from several main suppliers which they modify to their own tastes... Yet, NuPrime manufactures their own modules and is the best Class D I have heard with the NuPrime ST-10. And, that is not even their best. People overlook this company not realizing they stirred a lot on interest in Class D when they were NuForce, now NuPrime. |
@nugat The website is incomplete, and misses the nc1200 : https://www.stereophile.com/content/theta-digital-prometheus-monoblock-power-amplifier And... why does 85C matter? All amplifiers are thermally limited. There’s no evidence that the Hypex modules cannot handle their rated power for extended periods of time if properly cooled. https://www.stereophile.com/content/theta-digital-prometheus-monoblock-power-amplifier-measurements The same is true for ICEpower modules. Stick them in a closed wooden box and they are not going to be able to perform to their spec as well as in fully heat dissipating enclosures. On the other hand, in a normal enclosure, I defy you to get those amps anywhere near 85C/185F |

When pressed on who their supplier for modules was, they refused to answer. That does not mean that they aren't actively involved with the engineering types of decisions. It just means that they are not a semi-conductor company. |
@erik_squires NC1200 is for select customers only, and has been mostly replaced by NC500. They have the same power specs for 4 and 8ohms, the 2 ohm power output rating is higher for nc1200 .Datasheets can be easily googled. Bruno Putzeys designed all n-cores with "the same sonic signature", which did not help the NC1200 "high-end" priced unit. Icepower 1200AS has a peak power rating of 1250wpc (4 ohm, 1kHz, THD1%) however "continuous output power without thermal shutdown" is 280 wpc for the same signal (page 11 of the manual). The test is conducted with the module mounted on an additional heatsink with Rth=0.8 K/W, free airflow (page 11). Let’s keep in mind 1kHz sinewave is not music. AES/IEC recommend pink noise over a decade (IEC 40hz-5kHz) with a crest factor of 6dB to imitate a typical musical program. |
