Best practices when conducting a DAC comparison

A recent blind test with a large group of listeners showed no statistically significant differences with 24/96 pcm. I fact, if anything, there was a slight preference for the 24/96 pcm. The test methodology was not perfect, but I have seen nothing better thus far.

@aberyclark   Thanks for the tip on The Beatles 'Come Together' track. I'll give it a critical listen.

@gdhal   Thanks for your ongoing thoughts and advice.

if you don't hear a significant difference in the first 30 seconds then keep what you have!  Well that is my opinion anyway.  Happy Listening.

So if a recent blind test indicated that piece ‘A’ is the best, would you go out and buy this without hearing it 1st? I don’t give a s$&# if a group or a reviewer indicates this it that, I would have to listen to it 1st before spending a dime on it.
if my ears hear a difference between pcm versions, or DSD, flac/aiff, or MQA, then I will pursue that format.

Personally, I let the reviewers do the heavy lifting.  I read all of the reviews I could find on the DAC I was interested in and paid attention to the associated equipment they were using.  I was interested in the Auralic Vega nad purchased it based on the reviews of several seasoned audio/digital audio reviewers and decided to purchase the DAC based on what their observations were.  I believe I made an excellent choice.  I live in Cleveland and when I purchased the Vega, there were not many dealers that were well versed (or equipped) with digital audio gear.  Just my 2 cents.
