Let me ask it differently: What is the benefit for the diy community? Talking about companies, amounts of power and specs without the possibility to discuss the design and derive ideas to make people start building their own amplifier looks a bit strange. As long as you are not promoting your bossís amplifiers, its fine.

A DIY range are from simple job like fixing a couple of bolt and nut until designing a complete kit.

What is the purpose of this thread if you can't disclose a schematic and can not talk freely about the design?

for the same reason that Hypex UcD and NCD and other amps are discussed.

you cannot be selective in allowing commercial-like posts. Either you allow them all or you don't allow any of them.

As to what it is for DIY, I guess for inspiration and ideas for the DIY folks.

If you think it is commercial-like please report to admin to close it.
Else please stop useless discuss.

the prices are really attractive. Are those modules in production, or used by anyone in a commercial setting? How do the modules sound? any reviews on them?

the site actually has quite a lot of information and some of the daughter boards look like to use gate drivers. do you mind sharing al ittle info on that?

Thanks and this looks like a great product.

How about FQA24N50?
There is only one problem with it: very high Qrr. This is why the amp can't be loaded with lower impedance.

how did you conclude that on an amp that you haven't tried? and how low is "lower impedance"?

The Q isn't too high for high power MOSFET. It is current not Q limit the load impedance.
