This bit isn’t accurate. Have you priced them recently? We have. Using those modules would cause our amp to be more expensive than it is now.
Of course it is accurate. There are Hypex nc500 and Purifi amps, complete, from several sources, that are around $1000. No, they don't have a linear supply (they don't need one), no, they don't have a flashy case, nor do they have something you have to hide. They have decent warranties and companies that stand behind them. They are easy to repair and update. And most have a 2 to 5 year warranty, compared to your 3. And let's not forget, these are 400W, 500W into 8 Ohms, in other words, double the power or more than your 200W into 8 Ohm amps.
It's hardly a close comparison value-wise.
I fail to see why you keep repeating the bit about how it would make your amp "more expensive" to use 3rd party modules. So what? All that tells me is your modules must cost you very little, making your amp even more over priced. There must be at least a dozen or more companies out there who have figured out how to make a 3rd party module class d amp for less than half the price of yours or less. Maybe you need to up your game.
Less expensive than the other class d amps it competes against? So it's the least bad value of the bunch in the over priced status amp luxury market? Congrats.
I have no personal agenda, other than to call out over priced, under performing products when I see them. Audio is full of over priced products that don't measure up to far cheaper alternatives. I have no doubt your amp is well engineered, well built, and performs well. It's just not a good value, in comparison to other class d amps which have flooded the market, in my considered opinion. I am sure it will sell well, though I would not necessarily consider that a reflection on the amp itself, more further proof that audio is full of insecure, status seekers who like to spend extravagant amounts of money on products to assuage their frail egos.
