RE: Norm is 100% right when it comes to the Null hypothesis

Tony, well, I guess this is where the discussion of DBT's specifically and perhaps subjectivism vs. objectivism generally end...

I believe I understand what you're trying to say about the null hypothesis and Norm's use of the term isomorphic. I approach audio pragmatically and in situations where DBT can't prove a difference, I'm quite satisfied that MOST LIKELY there is no difference and await the next experiment to show otherwise.

I don't think this is unreasonable, it has been 30+ years with the CD! All we seem to see are reports like Meyer & Moran (2007). I think there are sporadic reports on Hydrogen Audio that stuff like high bit-rate MP3's can be ABX'ed but generally this is for stuff like castanets rather than real music. Other paradigms like audio differencing has not been able to add anything more.

I have never seen experiments of hi-res digital being differentiable from 16/44 in music or vs. mic feeds in controlled settings. As such, I'm not sure how you can say CD's as a whole sound "wrong". Sure, there were some really bad CD's back in the old days on equipment that were not fully 16-bit capable, mixing/digital manipulation done in low precision, suboptimal resampling algorithms, etc... I bet some people got pissed off at CD's for missing pre-emphasis flags that sounded thin and brittle (I ran into this the other day with a first press 1984 Howard Jones "Human's Lib" - once you de-emphasize properly, it sounds quite good). Of course things are no better these days with crappy over compressed loud recordings and every pop tune sounds artificial and Auto-Tuned(TM). These IMO are not issues with the core technology.

Oh well... I think that's all I gotta say. Time to put on a recently acquired Zinman/Tonhalle Mahler No. 2 for the evening. I promise not to engage in any more discussion on DBT/ABX for the rest of this year :-)
