Several years ago we applied some different design. At the highest rang we applied the ACSS technology, in middle rang we applied the diamond difference technology, in low rang we applied the classis technology as the circuit of our Moon, Earth and Sun. Like the Compass release in 2009, it is applied the amps as the Earth . This circuit still applied in some brands as the main amp technology.
But I still can't happy of the coloration of the non-ACSS technology , I always want to improved the gears but the non-ACSS technology can't let me happy. Even the lowest products, I still wish can applied the best technology for the best neutral sound . So now we applied the ACSS technology in all rang procucts.
The popular digital technology is not mysterious . Understand the PDF files , most designers can design the chips in the products.
The popular chips AD1896 not the tea of mine, so I never applied in our products , I prefer spend a lot money design the DSP3 had better performance .
If I just want to design a products for watch, I can easy add the AD1896 chips , but that is not my mind.
