Bluster is never a way to win a debate.
What you didn't read were the reviews. Perhaps anecdotal evidence like that means nothing to you, but FWIW the comments we get from reviews are strikingly similar to those from our customers, which can be seen on our feedback page. When lots of people say the same thing over a period of years, those anecdotes take on more weight.
Yes, its more expensive than your old Hypex, which is an excellent design.
What we've found is that with a lot of Hypex and other designs from the godfather of class D, Bruno Putzeys, is that things like the input buffer and power supply have an enormous impact on the way the circuit will perform. The Hypex modules were sold as modules only so someone had to buy them and put them in a box to make them work. If they skimped on anything the resulting amp would not perform as well as it could.
I think that is an enormous part of why class D has not had good acceptance in high end audio. I've met plenty of people who have said they will never try a class D amp again. Its not the fault of class D or the module; just poor execution which prevented the module strutting its stuff.
So yes, our stuff is more expensive (still a lot cheaper than the tube amps to which it is superior) but you have a nice chassis that survives shipping with ease, a properly built and protected power supply and the input buffer integrated into the module; all easily serviced and updatable.
If the cost is all that is stopping you that's no worries on my part. I've noticed that the best horn systems (of which IMO the Klipsch are not an example) aren't cheap either.
