Nice review! Some have reported that they find them lacking in treble and air compered to Audeze. What’s your opinion on that?

Nice review. I think I will like them ; 'dark'.

I really enjoyed this video Amos. Very detailed review with great presentation and telling exactly what the great features of the Oppo PM-1 does

Very informative review. Thanks.

Informative review, thanks.
 
Any comments about how they sound, driven directly off portable sources, without a dedicated h/p amp, compared to other high SQ cans? 

ITS HIS FACE!!!!!!!!!!!!!!!!!!!!!! Not sure Why I am so surprised by that, 
 
but UGH another DARK sounding planar >.>, but if they aim to steal some LCD 2 customers I suppose that's a good move on their part 
 
I've got a demo LCD 2F atm, it's not a bad headphone, and even with Fazor it's still a touch to dark for my tastes and all of my music 

HE-6 is not dark, and it's planar, and it's detailed.  Problem is you need a powerful amp.  People driving them with speaker amps.  Very informative review.  Thank you.

Very nice and balanced review...well done! Many thanks.

@ Silver Ears, yea I know the HE 6 is not bright, the issue is ofc with getting a powerful enough amp, I enjoy my HE 4 very much, but I doubt my Audio GD 10ES2 will do the HE 6 the justice it needs, although people say under powered the HE 6 is brighter lol [which sounds about right for what I like in a headphone] 

Given my experience with the PM-1, I would not categorize them as "dark".  They are not treble-leaning in character, but neither are they "dark" with respect to falling short on resolution of treble detail and/or obscured by the treble being swallowed up by disproportionate bass levels . To the contrary, the PM-1 fashion the treble like fine filigree.  The treble is there with delectable detail, but not in a forward manner.  Plus the PM-1 are comparatively balanced on the bass side so as not to create a lop-sidedness versus their treble levels.  
 
To me, the LCD 2.2 ARE dark, and sorely lack the treble sophistication/deftness of the PM-1.

+1 to SilverEars' comment on the HE-6.  A very clear and balanced presentation, in just about every respect, when powered adequately.

Thanks...very nice, informative reviews!
 
Planar Revolution!

Very nice job or presenting data and giving enough information to make our own determination.  Solid information and I am always pleased when someone gives their own opinion on a headphone review.

Thanks for the comments everyone. @DougD Good point! I forgot to mention portable listening. I'll write something about that shortly. 

Great review mate.

Is Jude off-loading his HF TV to Amos?  Will we get weekly reviews from Amos?  Would be nice.  Daily would be nicer, as Amos will have 365 phones in a year reviewed.  Jokin.  It's nice to get video reviews.

Nice bit of signage on the wall there mate! 

@warrenpchi: No thank you! It is my first ever meet sign!
