Hi there,

The claims I hear for audible differences existing for different electronics amount to frequency response, noise and distortion.

These distortion graphs are between the two I/V stages of a DAC :



And :



The claim is that these DACs measure flat, but the measurements show the effects of certain filters at play. Looking at the distortion components, is this enough of a difference to cause gross audible differences? The claims I hear are that different filters used in DAC design can result in audible differences irrespective if that DAC measured perfectly flat.

What do you think?

Just out of curiosity, did any of you watch the whole presentation? What did you think? Any good points there .. or is it basically snake oil?

If you are curious enough you might have searched the forum in order to avoid a double-post...
