How long has the MA-1 been made, does yours support DSD? It seem I read somewhere Meitner has software upgrades available, can you enlighten me on that. In the world of high end dac I wonder how the MA-1 compares with the Schiit Yggdrasil probably not a fair comparison considering the cost difference between 7000.00 and 2300.00 possibly making your Meitner a real bargain,
