I know this thread is littered with comments about how the M0 software sucks, gapless playback doesn't work properly, it doesn't have replay gain or phone-remote-control features, etc., and I'm not here to defend that. I'm not in anyway affiliated with Shanling and I honestly don't care what DAP any of you buy next, but one thought - be careful what you wish for. I suspect one of the reasons why the M0 sounds good and measures well is precisely because it doesn't have all the cellular/WiFi radios and Android OS crap under the hood.
What strains credulity is asinine statements like this. So you'd be perfectly happy to accept a best-to-worst ranking from a reviewer who performs sighted tests without bothering to SPL match, who has a vested interest in keeping the free review units coming, who has different hearing than you, different headphones than you, different test tracks than you, different subjective priorities than you - yet a purely objective measure from an audio analyzer "strains credulity"?
Most people seem to have read the disclaimers, but since you didn't bother, I'll repeat myself. This was one particular test condition only (150 mV into 32 Ohm), and the devices have simply been ordered by one particular metric (diffrogram median), which might not be top priority for everybody, hence the ranking does not imply one device is universally better than another. I clearly stated this is still research. What it is, however, is objective, repeatable, and shows weaknesses with even the most expensive devices on certain aspects of the test vectors.
If you prefer, you can just mentally re-order these devices from most-to-least expensive. There you go. Now no part of your brain needs to be strained.
