Dolstein,

As I understand it, changing the drive ought not impact the ability to play DVD-A.

The issue has been caused by the failure and replacement of the chipset.

See this thread for more details.

Best way to check is play a DVD-A on the unit.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
