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.

what gets me is that when somebody gets called out on a error, they get all butt hurt, but they dont mind calling out others.

"   My real point was, I personally am _shocked_ a Mytek rep would say this and let it go to print. "

I wouldnt worry about it to much.....

cheeg : 

My bad, I _thought_ that while sober I had seen the insides and it looked like an ICEpower module. I stand corrected, and obviously overlooked that in the article.

Thank you for correcting. 

Best,

Erik

Well, I don’t own stock and won’t make money either way, but that kind of attack in the press is really not one I am used to.

Anyone have experience comparing Pascal vs. Hypex amps?

The Duntech Sovereigns are specified as being 3 to 4.5 ohms. That is well within what should be the Hypex’s comfort zone.

Not if there's a -50'-60' degree negative phase shift also at 3ohms, then the amp could be looking at nearer 1ohm.

Mytek ultimately chose an amplifier module from the Danish company Pascal

And this could indicate Pascal get them from China and mod them. As are Red Dragon and Rowand Research

Not exactly how this works, but yes, large phase shifts mean high currents near zero volts. Hard for most amps. Would be nice if we had impedance graphs for the Duntechs.
