No, I'm saying that this is very much distinguishable without exotic hardware, on music not deliberately created to expose compression artifacts. And at a bit rate higher than what you claimed to be transparent on non-audiophile setups. And calling <20$ headphones (that includes an in-line microphone) on a Thinkpad's built-in headphone amplifier "audiophile" seems inappropriate. I do hear a difference (on FLAC) between those cheap headphones and some ultra-low-distortion 2-way half-open headphones, with the latter being notably more clear. You said 64k stereo aren't distinguishable from FLAC with normal, consumer-grade listening equipment. I said I hear a difference between 80k stereo and FLAC using a laptop built-in headphone amp and the cheapest headphones that didn't look like a consumable.
