Dear Redwick
I am not sure of the differences between the MK1 , the MK2 and the MK3.
However the earlier DAC64 where fitted with only 1 BNC input and had no
on/off switch. The latest spec is the MK3 and has two BNC connector to
allow the interface to DVD-A transports and an on/off switch. Chord however
have launched their new transport (£4150) and it is for CD only and cannot
be upgraded to DVD and DVD-A in the future. For those with earlier DAC 64
there is no upgrade path to the MK3 with the two BNC and on/off switch.
Info extracted from the Chord people at the London Hi-Fi show.
Regards Richard

of
this DAC ?

I understand Mk3 is the current.
