have anyone came form WM1A or WM1Z and would like to express comparison with the M6 Pro ? "From memory" can help too...
M6 pro (early analysis, so take it for what its worth), and I only run balanced: The M6 pro has much better power, far more exciting and energetic playback (could be relative to the significant power increase) versus the wm1a. The amp tuning is that star of the M6 pro, they are neck and neck with the R6 Pro, imo. The M6 pro has the blacker background, no noise at all. Most Shanling devices (this is my 4th) have a very velvet smooth output, that is not the case with this device. The amp is an exciting, toe tapping experience.
Battery life is pretty darn good on the M6 pro, especially if you disable some of the apps. The Play Store mod works fine, although I do wish the device was running Android 9, for security reasons, since you do have to use your google account to verify some apps, while online. The dual DAC chips are clean, but I would have preferred a single 4499, as I can "hear" a difference between the 97 and 99 chips, when using the device is USB DAC mode, vs my desktop setup. Just subjective, no measurements to back up my "hearing". I prefer the 4499 architecture in how it sounds.
The wm1a still has the better software, as the sony OS is just excellent. Man if Shanling can get a contract with Qobuz/Tidal for an app to run on the Shanling non android software that would be PERFECT. The M6 pro is more portable and more ergonomic, feels lighter and better in the hand, the wm1a feels fatter. M6 pro has the better screen. The wifi and bluetooth are both EXCELLENT, far better than the Ibasso devices (wink wink). The processor is snappy, but there are still some slight menu hiccups with NON
NATIVE apps (probably because of android 7.1.1). That is the fault of the other programmers not Shanling. The
Shanling app works very quickly, I am not the biggest fan on the menus and layouts and file structure though. The synclink option is great though. If you stream, the wm1a is just not applicable in 2020, so I while most of my playback is from my sd card, without streaming, I just don't get paying $1,000 for a wm1a is 2020. offline Tidal is bitperfect, but I don't think MQA works, who cares though. But Ibasso wins in this regards, even the DX160 handles MQA (IF you can get your wifi to work lol).
Stage is about the same, midrange tonality leans towards the M6 pro, as to me the M6 pro focuses it's energy in this area (mainly a function of the chip imo). Treble is about the same, neither of the two devices are what I would call bright. If you want a bright device, I would recommend a DX220 (or DX160). Bass is a win for the M6 pro, again probably more due to power drive, than anything.
No case is included, and at $750, that sucks. The case is very nice, but it costs another $35.
