Just had an email from David at cypherlabs. He confirmed the chip is not the one mentioned here and went on to add that it is not just about the chip but all the other components that make up a DAC which affect the sound as well which I feel is quite right.
We can get caught up on various names and so called upgrades of components when if something is done right in the beginning then it is simply right, sure, time may pass and technology changes things but it has to be a pretty profound shift to make considerable changes.
When you see, as one does with this component it being used in really high end home based systems and satisfying folks who have spent hundreds of thousands on components it speaks volumes of the basic rightness of this product.
Have you noticed as well that unlike some other much lauded giant killing products featured on headfi this one has just quietly gone about its business of providing users with a reliable, high quality sound, no constant up grades or new shiny stuff to make the previous stuff obsolete over night, no buggy issues or complex needs to simply hear music, just plug, play and revel in the music which is all it is about after all!
This is a great information and I totally agreed with the comment from CypherLabs.
