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.

N-core   continuous power output is thermally limited (like any other amp's). You get those figures in the OEM manuals. Currently the top OEM  n-core is nc500OEM. When you pair it with SMPS 1200/700 you might get the PEAK performance of 700wpc.  N-cores assume that 100wpc continuous  is deadly enough for anybody's ears in  a typical residential room . And rightly so. The assumed crest factor of 5-7x gives peaks of 700wpc which is sufficient for most transients.  Hypex is one of the very few companies which are  open about what the real amp power output is . The continuous power output (RMS power is a misnomer) should be tested with standards at least like IEC 60268-5. 
Those numbers are on page 5 of NC500OEM datasheet. Go to hypex.nl.
Overtemperature is indicated as 85 deg Celsius (page 4)
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.

The website is incomplete, and misses the nc1200 :

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.

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
