^^^This, plus all he has to do is see the iPhone and he can make his comment, especially if it's playing from the headphone jack and the volume output on the phone is low. He'd have to do at least five things to prove his point to me.
1. Have a CD of the same song.
2. Level match the input signal of the iPhone and the disc player.
3. Make sure both signals pass through the same DAC.
4. Play them at the same output volume, using an SPL meter to verify, and make sure tone controls, etc. were identical for each.
5. Close his eyes and let me switch song between the CD and file in a random pattern with a brief pause in between like A/A/B/A/B/B/B/A/B/A/A/B, then be able to pick out which was which.
If he could do that, I'd be impressed. I'm not impressed when he see my iPhone, listens to one track, doesn't compare it to anything for reference, yet proclaims it compressed. Compared to what/ Could the original recording have been compressed? Today that's certainly too often true, so, yeah, guess what, a recording that's compressed in the studio/mastering process sounds compressed when played back.
Of course, he'll never do that, because you're just supposed to believe that he can hear it; 'cuz he said so; otherwise, it's harder to up sell you.
