Yes, adding DAC functionality will increase the cost of K7. This is really a waste for customers who have one of them.
However, if the DAC and AMP are separated, the cost will increase even more. Because we need 2 sets of power supply, 2 sets of metal shell, 2 sets of processors and so on. Customers need to pay more to get this combination if they want both
Well, let's go back to the original intention of the K7 project. We actually want to design a DAC& product with stronger THX AAA power amplifier. In other words, the DAC part may not be so strong,but it will not be too weak. With DAC inside, some users can use it more conveniently.
This is why we discuss the meaning of XLR balanced line output, and why we discuss which DAC will be suit. Such as ES9028pro, ES9068, AK4493×2,AK4497, or Cirrus logic CS43198×2
