PS AUDIO DIRECT STREAM DAC OR DCS ROSSINI DAC

This is the type of comparison that needs to be done in a direct A to B method.  In terms of perception,  pedigree, status and cost the DCS occupies a different class.   One thing I have  learned is that you must actually listen in order to assess the "true" sound quality of a component. There can be (sometimes) unexpected surprises and outcomes when this approach is taken.
