Hi-fi audio signal chain -- no more sigma-delta
You're right. Let me rephrase: a theory that has not yet been disproven.- 22906

Phase in Audio Signals
Thank you to all readers; I would like to expand on points #2 and #3 for the benefit of the community. The reason I am against digital filters is that I believe once the signal has been sampled, and therefore transformed to discrete time, further manipulations can only hurt signal integrity and...- 22906

Hi-fi audio signal chain -- no more sigma-delta
Thank you; however, that's not what I'm doing. My technique is simply to propose a theory that can't be disproven. That is the definition of scientific truth.- 22906

Hi-fi audio signal chain -- no more sigma-delta
jcx: While I can't say I appreciate the cynicism and utter lack of evidence in your post, I do appreciate your attempt to discredit my ideas. Hi-fi audio does require static linearity, and "perceptible distortion" is not a valid criterion for judging the fidelity of an audio signal. -...- 22906

ubecko, I applaud your attempt to understand what's going on; keep up the good work. Your new friend at Head-fi, m3_arun- 22906

Hi-fi audio signal chain -- no more sigma-delta
I hold a BSEE from UCLA. You can make fun of my degree all you want. Your claims about hearing processes are not relevant to creating a hi-fi signal chain. Whether we can hear non-linearities in the system is irrelevant to the fact that they are there; if digital audio was based on the...- 22906

Phase in Audio Signals
Hello Head-fi; I'm back. This time to advance my views on phase linearity in the audio signal chain. 1. Only planar transducers (or phase-linear transducers) should be used in audio 2. Digital filters are completely unnecessary and counterproductive to hi-fi reproduction 3. The maximum...- 22906

Hi-fi audio signal chain -- no more sigma-delta
I want to pre-empt some of the responses that have yet to be posted; and this will NOT be my last post on the topic. Delta-sigma manufacturers have used various statistical linearity measurements to cover up the lack of resolution of the converters. There is no substitute for static...- 22906

Hi-fi audio signal chain -- no more sigma-delta
Jokes aside, after doing some more independent research, I've realized that the parameter I am looking for is called "static linearity." I predict that the static linearity test will show the R2R coming out on top. Thanks to all for playing along for so long.- 22906
