Forking from the cables thread to a discussion of whether hi-res is audible.....


While on the subject of embarrassing testing...

Let me preface this by saying I have invested in hi-res audio tracks, both on my server and in my Qobuz subscription. I've always felt I could tell the difference, although there are duds in hi-res just like redbook. And some great redbook recordings.

Going through this test, particularly looking at the control groups, is certainly humbling.  I particularly like the "hardware reviewers" group.

Could be.  The initial reason people objected wasn't because they needed extra bit depth or higher sampling to hear more, but because the filters required for 44khz produced at least measurable artifacts in the audible range.  But oversampling was the answer for that.

If you look at the link I posted, the listeners were using a range of high end equipment.  And the 16-bit resolution was packaged in a 24-bit file.
I think so. One possibility I've considered is that the studios that put out hi-res recordings may, on average, be more conscientious about quality.

Also, higher bit-depth has significant advantages in the recording and mixing process.
And yet blind listening tests consistently reveal we hear less than we think we hear when sighted.  Complex indeed, but perhaps not due to the biomechanical sensitivity in the ear so much as interactions between parts of the brain.
@geoffkait as the OP I can assure you blind testing was there from the very beginning of the thread .

In general, I think those of us who have invested in this should remain open and humble towards all possibilities, if only to further our pursuit of happiness.

I don't mind stating my priors, and I'd be happy to be proved wrong:

  • Personally, I find speakers the most important by a country mile.  No problems applying money and time to speaker auditioning. 


  • Amps need adequate power and reserves for their load (no small feat for some speakers).  That difference is large,   differences beyond that are subtle.  This isn't surprising given that amplifier optimization has been critical for years in many fields beyond audio. 


  • With sources, however, I believe I hear big differences.  Given testing results, I'm probably way overconfident. Nonetheless I am convinced enough to spend money here.  It's possible this is a hangover from my vinyl days.  With CDs I only thought  heard a real difference when  I listened to the first Theta DS. And nowadays, the front end is where all the features and ergonomics come in.


  • Cable differences, if they exist at all once capacitance is equalized and guage is adequate, seem, at best, an order of magnitude smaller than amps.  I think the industry may have fallen off the deep end on that one.  Nearly Tice Clock territory. I have old Cardas and Analysis Plus speaker cables I bought in more foolish times which I just re-use, and Mogami balanced interconnects, which is likely what was used in the studio. I do like to work with a well-made, well-terminated cable.  But that isn't a sonic judgement.


  • I clearly spend too little time on room treatment, which is very audible.  However, I have to stay married.


  • I have noticed that poor build quality immediately biases my listening judgement.  It's like I'm waiting for something to be off.

My hearing rolls off above 16khz, not bad for my 55 yrs.  But I've felt more or less the same way on all of this since my twenties (my Magnepan era).  
I'm more concerned about the things we can't hear, but convince ourselves we can.
