Hypex N core module

We've already been listening to the amp. FWIW the squarewave response you linked does look pretty bad. Our tube amps can do better than that!

Obviously we're not letting this thing out without it doing what its supposed to do.

The thing is, you can have all sorts of issues when building a switching amplifier. The layout of the boards is critical- if not done right you can get stability problems. The little 'dimples' in the squarewaves you linked say to me that there is a suppressed oscillation in the amp somewhere. The squarewave should have been flat across the top, but its not! That's not a switching frequency thing as it is a stability thing.

Now the parts we work with are not that expensive, but we found a way to eliminate deadtime. This allow us to switch at much higher frequencies.

Naturally your not going to tell us how it’s done, I’m hope for you that you can do it, but also sceptical at the same time, as minds more attuned to solid state Class-D topology than yours have not succeeded, save for Technics who are half the way there.

Of course it can, any linear amp can, not just yours!

It’s very good for any Class-D without the need of special external output test filters.

I'll be happy to after the patent is approved. That EE turned out useful after all...

Just an FYI, and to correct any misconceptions about us.

We used to use all the Hypex modules from the NC1200 in the VERITAS Monoblocks, down to NC500 in the Taranis. While we have a superb implementation of these modules,  based on direct comparisons done by others to the same modules in other units, we understood there was more to be had.

We will shortly be introducing our proprietary designs which takes the level of performance up an order of magnitude, and rivals any of the best of classes available. Using our proprietary ZXOL design that has no feedback loop, we are able to achieve this exceptional performance. 

We are stepping that up even more with other design and engineering techniques.

Look for us at Munich 2018 in ATRIUM 4.2 E226 where we will be showcasing this exceptional sound.

Reviewers will be getting their units in February/March. Some have the proof of concept heard it at CAF 2018 and their impressions were in the November Newsletter.

Here is a sample of what is to come.
