That is not accurate, they didn't use the APX555 to improve their products. They have one of the godfathers of DAC design, Mike Moffat, who started making them in the early 90's. I've owned several of their dacs, and presently own the Gungnir and Modi Multibits. I enjoy them both, the musical and organic sound of both is quite enjoyable. Specs do not tell one how a component will sound
The Modi 3 was a statement by Schiit, and an acknowledgement that some audio hobbyists ignore their ears and put specs and other numbers first. Topping has built up a forum to market their dacs and spread the numbers and "science first" school of thought.
For anyone reading this, if you want to be able to hear the differences in dacs and other components, your system MUST be able to demonstrate the nuances. Speakers and pre amps are most critical for this, and speaker cables as well.
