ghdprentice,
The differences I heard were in the background details The background was blacker you could hear fine little details in the music way in the background that I was missing with the Burmester, The b a s s was also better with the 861, don't get me wrong it wasn't huge differences but for a $22,000 US amplifier to go up against the $50,000 US amplifier and be better is saying something about the new MDCA technology that SIM audio has developed.
