On our 6 model AD converter shootout, the initial blind test differences seemed more important than became apparant over a two week period.
Also, attention shifted from the WOW this is great blind responses, to the living with/working with 'this actually sounds the most natural, most transparant' observations.
The one that jumped out as the most 'live'&natural (during blind testing) actually revealed itself as the most inaccurate AD converter ever seen here !!!
IMO blind testing gives very biased results, as one WANTS to hear certain differences - even if they are not there. They are only usefull as a reference.
The working with period actually convinced us NOT to buy the sexy, initially best sounding AD converter.
We bought the very one we were (initially) not at all interested in.
Three units.
Several projects later it is becoming clear that the quality of these units is indeed far better than expected.
