Thanks for the review man, can you please shortly describe how X7 sound with comparison to X5/X5ii+E12A combo?

@violencer : X7 has by FAR superior ESS9018S desktop DAC in comparison to PCM1792A in X5ii. E12A adds a little more transparency, but it's not enough to come close to X7 performance when comparing with X5ii/E12A.

Very comprehensive review, and you did a LOT of work on the write-up. Great effort,, and much thanks !
One suggestion though ... you did a many comparisons with other DAPs, and then tested the X7 with a long list of cans ... which, as a representative of the class of people not so intimately familiar with the available DAP and IEM models, I found became something of an alphabet soup. Stating the brand names also would be helpful. Some models I recognize immediately (e.g., PM-3, I own that), but others caused the brain to stop reading and start trying to make association between model numbers and brands.
