That's awesome !!! Enjoy .... Its such a great amp. I am now using it with a RME ADI-2 DAC and it's an incredible combo. The RME has a very good headphone section...or sections I should say. If I didn't own the Quicksilver I would probably be happy with it. The best feature of the RME is just that, it's feature set. 5 band PEQ, selectable digital filters, bass and treble, loudness. To name a few.
The grip that Quicksilver has with bass is scary. Plus it is clear as a bell at any volume. I buy and sell a lot of gear and these two are keepers, especially the amp as it will never be obsolete....dacs do have an inherent obsolescence.
