Feature set, some DACs have stuff like remote control, multiple outputs, different inputs, filters, Bluetooth, DDC, but unless you need any of those, D10b already outstanding.This is good to know. Thank you. Though, the price is increasing too! Is there any reason to use a more expensive dac than the 10Db? Aside from a quality digital to analog conversion and good numbers, what features do a fancier dac provide that the 10Db doesn't provide? It seems that the features should be in the amp, not the dac.
