People loving the PM-1 is great. I mean people love Audeze too and this little guy seems to give them a good run for their money. Also, it is good that Oppo managed to do very well on their first try!
Then there are us folks who are looking more at a pure neutral rather than warmish neutral. Different ears, different taste.
There are few headphones who do that right and admittedly you can't avoid a teeny bit of fatigue most of the time. But these headphones that manage to go there, from one extreme in the low range to the other extreme in the high range, while still sounding very clear are a treat to behold for my ears.
Again, all subjective and all down to the taste. I'd certainly love to see Oppo compared to something other than Audeze, something more neutral or bright and see how they fare.
Like the Alpha Dogs!
