Floresjc you were very lucky to have snapped up that DAC MK5. We don't see these units back here and I had just updated the used equipment page on our website.
If you are loving the DAC MK5, you will be astonished with the DVA Digital preamplifier. This paired with our M225's is the best sounding system we have ever produced. I haven't seen Frank enjoy his system as much as he does with these pieces. The best part is we have caught up on our backlog of orders for this unit and can now ship immediately.
