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.

If your going to copy and paste something from an article, you shouldn’t do just part of it.

There is a perfect refutation of this in Dostoevsky's Crime and Punishment.  I wanted to quote the part but ... Oh come on?? 
Rogue is a poor example of an amplifier. I have little ATCs that Rogue couldn't drive comfortably.
Class D amps remain controversial in high-end circles. I did a lot of reading about them before finally buying one (a used Wyred4Sound ST-500 built around an ICEPower core) to use w/my ATC SCM12 Pros. I was struck by how balkanized much of the commentary was: armed camps w/Class A and AB lovers on one side, and Class D lovers on the other. And the Class D ranks were riven with dissent over the positive/negative attributes of various amp cores (Ncore vs ICEPower vs Pascal). 

I don't have a pair of big speakers w/subs built in to test the Wyred4Sound on. But I can tell you it drives these ATCs extremely well. Among other things, I'm getting the best bass I've ever heard from a 2-way speaker. With a Marchand external/electronic crossover & sub in the system, I don't need anything below 80Hz from the ST-500; but I've done plenty of listening without the sub, and the bass is very fine--impactful & tuneful all the way up through the upper bass. Plus there's none of the etched upper mids or treble one kept hearing about with Class D amps 10-15 yrs ago.

Does that mean I'd use Class D if I had a big, expensive living room system? Maybe, maybe not. But IMO, Class D is definitely "on the table" now as a quality sonic option in various high-end applications.

From a couple of manufacturers I am familiar with (B&O and Hypex), the modules offer two inputs. One fully buffered, and the other low impedance.

The unbuffered and low impedance input allows the opportunity for OEM’s to make their own input stages. From tubes to discrete class A amps, you name it.

Of course, it also matters how many you are buying. If you buy 10,000, I am sure B&O or Hypex can accommodate custom engineering changes. :)

Best,
