Did you get the optional HQ analog module? If not, an analog source may not be the best test.
Definitely try the digital input, and run Room Perfect. Room Perfect noticeably improved bass for me. I have a stand-alone file server (Bryston) so haven't tried the playback interface on the 3400.
I recently got the analog module and now have my Yggdrasil DAC feeding into it, using XLR. I will try other analog sources at some point. But to my ears, using the Ygg offers an improvement over the built-in DAC, even if it seems a bit counter-intuitive.
