Question About DACs

These forums are fun to read, but it’s just for fun with more opinion than fact.  Sometimes fantasy.
But still it’s part of the hobby. Addictive to some nice people that care to post and read. 

  My suggestion is to listen to
what you purchase first.  Measurements are useless compared to what you hear and like.  Like and pay for what you think sounds good.
 Today’s sales model stinks for those of us who enjoy shopping in a real world.

What CD player specifically?  How implemented matters often more than what chips are used. I can use chips well or badly, simple as that.  I have compared back to back a Schiit BiFrost multi-bit to the same designer's $4000 player circa 1994 9Theta DSPro) Closer than one might imagine, and the Theta, in all listener's opinion, was just a smidge BETTER. So much for today's stuff killing yesterday's. OTOH given he price delta its a great compliment to the modern day Schiit. So-so QC however.

Let’s say the frequency response is within +/-0.1dB, distortion below -90dBFS, crosstalk better than -90dBFS, no aliasing or images above -90dBFS due to the reconstruction filter, volume linearity within +/-0.5dB down to -120dBFS (20Bit), jitter suppression better than -90dBFS, etc.

I would like one reason as to how it could not be transparent.

If you have heard differences while blind listening, then it was an issue with the test (not double-blind, not level matched, and not quick switching), or it’s simply differences that don’t exist, which could be verified by also doing an ABX.

People just don’t want to hear that their $5000 DAC isn’t audibly better than a $250 one. 
 
How can we hear things that aren’t picked up by measurements? Solid state DACs aren’t like tube amps where the final sound output is based on the interaction between the tube amp and the speakers, a solid state DAC has a fixed output.

Think you've made your point, pal! Though nobody is interested in arguing it.

“People just don’t want to hear that their $5000 DAC isn’t audibly better than a $250 one.”

Not looking to land on either side of this argument, but from looking at the length and energy that goes into posting it seems that 

“people don’t want to hear that their $250 DAC isn’t as good as a $5000 one.”

is is an equal if not greater force in this debate.
