asymmetric apodizing filter


I have the esoteric K01 and it offers the standard filters and the newer filter designed to reduce preringing. They surely sound different. I would like to learn more.

Do the asymmetric or apodizing filters come with sonic tradeoffs or theoretical tradeoffs? Do they compromise phase linearities?

Thanks

We can talk about various advantages and disadvantages but it all comes down to your own ears. Some won't like different filters because it's just not what they've become conditioned to. Thirty years of "brickwalls" sets a de facto standard of sorts.

Newer DAC chips, like some of the Wolframs and ESS Sabres, have multiple filter choices on board but the surrounding circuitry and implementation can make a large difference.

Related topics, in a more analog context, might come from terms like "group delay" and "Bessel filters".
