We are comparing to fantastic products that are; inexpensive, relatively high volume, and many times almost generic in design.
There is still a market for low volume (boutique) products that are designed from scratch. Using four paralleled LM3886 per channel is no simple exercise. Took planning and testing to make this work. Those costs are factored in.
As far as I know that output topology has not been used commercially or diy before.
So no prior designs to copy.
I do not know price in Russia. Should be better than the US price.
I cannot throw at the product. With crazy tariffs and shipping costs this may not be like printing money for them.
