RE: Why would I want selectable Digital Filters in a DAC?

Posted by Thorsten on September 1, 2015 at 08:22:28:
Hi,

The main reason would be that some Digital Filters measure very well when using something like an AP2, but the sound quality is not great.

On the other hand some of the Filters that many find good sounding (including no filter at all) measure, shall we say interesting, on an AP2 (here is one for the AP2 and 'scope jockeyes - how come often what measures quite poor sounds great?).

One way around this is to make the filter switchable, Ayre did this quite tongue firmly in cheek by labelling one position for the filter "Listen" and the other "measure". So AP2 and 'scope jockys can marvel about the great measured results while people who prefer to listen to music may choose what sounds better and not worry about what it measures like.
