More components. And ones that by definition become obsolete/outdated rather quickly, thus diminishing the value of the whole device. A pure analog amp stays the way it is for decades, and you can hook it up to anything you like. The built-in digital inputs would be useless sooner or later due to ever-changing/evolving digital formats. Aren't there also less line inputs available due to the inclusion of the digital ones? Haven't checked. Anyway, I won't be buying an amp with an integrated DAC.
