I Get mixed results when comparing them side by side . But one has played thousands of hours , the other only 50 . Both are spectacular soundwise ,but Bda2 is a little constrained making vokals a little more distant, and the bass is a tad drier (harder) and does not go as deep , I feel the bassthump in the chest more with the Bda1 .
I had to check the specification to see if they had the same output voltage ,because I felt the Bda1 was louder . Bda1 makes rythmic music swing more ,it has more PRAT , Bda2 is a bit more focused/controled( maybe) an relaxed .
Tonaly they are very similar .
I will let the Bda2 play for one more week and check again next weekend, but I am not returning the Bda1 just yet as it is still my favourite, but it is close.....
