Please see my test track list – most back-to-back comparisons used a subset of these songs. The grain jumped out with the mild songs early on the list, and continued until my ears habituated to the Clear after an hour or more. I stopped noticing the grain a few days after sending the loaner Utopia away.
I heard stark differences in the “air puffs” of the thump thumps in this heavily distorted White Stripes song. It is song 40 on my list. But, I used the uncompressed version from Amazon HD. The OG Clear was akin to the chest-thumping feel one gets at a live concert, but not so apparent with anything else.
