Got an apple remote today, the change with upsampling seemed subtle at first but the more I listen, the more I like. Biggest improvement is to the quality of female vocals, just such a natural and realistic quality. I'm also really amazed how well the K702 65th Anniversary scales with a quality source. It's making it tough to justify keeping my new AD2000X though it's a great performer in its own right. I'll have to do more listening to decide for sure. I'll probably still keep both unless I just sell them both and try to get an HD800 This DAC really makes me want to get even better headphones.
