In Reply to: RE: Schiit's spin posted by AbeCollins on November 17, 2016 at 21:43:42
"Spin", is the correct word for it. Most of that Schiit consumer sales argument is all too familiar from the audio industry. The performance needs of a missile guidance system, or of an MRI machine are different than those of an audio DAC. It's not simply a matter of those other applications having more stringent requirements, but that they have DIFFERENT requirements. Specifications good for one application are not necessarily good for the others.The notion of 'closed-form' anti-image filter is another example. Audiophiles are always trying to incorrectly apply intutive analog domain notions to the non-intuitive digital signal processing domain. The notion of the importance of retaining all the original digital sample values is an analog domain notion. All that's required for perfect signal reconstruction is the removal of all of the ultrasonc images. Retaining all of the orginal sample values is not required for perfect signal reconstruction.

Maybe I misread, but the close-form isn't about anti-image but about asynchronous sample rate conversion which is used for jitter rejection, not image rejection.
Still, I can say I really like the sound. :)
Best,

Schiit's spin is pretty convincing IHMO for those not wanting delta-sigma, for whatever reason.
Like audiophile cables, DACs are overcrowding the market so turn up the SPIN !
The problem is that sales spin is often complete misinformation. On the plus side, most Schiit products don't require you to take out a second mortgage on your home to purchase, so no great harm done if a Schiit product turns out to be less satisfying than the spin had led one to hope.

Oh, well, I guess that no real harm can be done for $50. One thing that I will say about such ads is that they do sometimes provoke intrigue regarding the details of what exactly they are so lathered up about - LOL.
