Mytek slams Hypex in Stereophile Amp Review

Mytek is known to have been using strange marketing methods, especially  for a pro originated company. I remember when Brooklyn came out they were advertising features worth "thousands of dollars"- I believe they meant the phono input. In my experience nothing beats
n-core in d-class. Recently I compared the new IcePower AS 1200 with nc500oem and the SQ factor is definitely pointing to n-core.

I have read the Stereophile review.
Apparently Mytek built those amps specifically to power their Duntechs.
Those speakers are a 25 years old technology with passive first order crossovers. A strange choice for a pro studio. The JA measurements of the Mytek amps give "respectable" figures. But the amps cannot be measured properly at 2 ohm, as they go into protection modes. So, low impedance performance is not an issue here. The Pascals strong side is their potential brute force, hence the 300wpc (continuous hopefully) metric. They perform nicely with subs, not so in the mids and highs. Ncores can reliably deliver 100 wpc continuous and 700 wpc peak. The heat dissipation becomes a problem. But when used in active architecture, n-cores are unbeatable on all counts. All in all, Mytek is a peculiar amp for peculiar 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)

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.
