I have received my pair of Peacock and went out to the park for a very long listening session. They have a very high db spl/mw, so easy to drive. I'm not someone who likes to use crazy words to explain the sound of a headphone, to help you out, i will list up headphones that i like or dislike for comparison. I believe this is more helpful.
If i mention EQ, i mean oratory's Reddit profile (not autoeq, there is a vast difference)
Dislikes: Focal Utopia (EQ), Focal Clear (EQ), Hifiman Arya (EQ)
Middleground: Hifiman 1000V2, ZMF Verite
Likes: ZMF Auteur (Low Shelf Bass, slight treble enhancement), LCD-2 (EQ), Susvara, HD800S (EQ), Stax SR-L500 MKII (EQ)
First things first. What annoys me with the Focal's is the shouty voice experience, with the Arya the annoying treble peaks that can't be solved with eq with further reduction and the overall lacking Slam/impact/punch especially with the hifiman's. The LCD-2 has great bass and slam factor, same for the Susvara, HD800S and Auteur, even the Stax after EQ, before its lacking in that department. What i like about the 1000V2/Arya is the sound that goes above your head and the presentation of the stage/size of the place you are listening to the music, because it sounds big without being able to measure the roomsize, because its sounds are more open in the nature, compared to the HD800S that always feels like an incredible big arena with a slight echo.
The Peacock is impactful and slams a bit less than the Audeze/Susvara, got the biggest soundstage after the HD800s and the sound goes above my head, similar to the Arya/1000V2. Singers are slightly recessed sounding, which makes the instruments and overall music presentation more forward and spectacular and the treble is never fatiguing, similar to the ZMF Auteur. The Subbass is missing and the quantity not enough for my taste, but i like the harman curve.
After fixing the Bass with Low Shelf 54Hz Q 0.7 10db Gain (Ifi Signature xBass) and giving a slight Treble Boost around 2bd starting at 6K fixes most of the problems with Voice and Bass quantitiy as well improved slam. I believe an oratory EQ profile could improve it even further, but i like the original presentation nonetheless, because it reminds me of the ZMF Auteur just with added improvements.
Of all the headphones i have heard so far, with or without EQ, is the peacock overall the best so far, because it got the fantastic non-fatiguing treble with more details than the Auteur, very good presentation of instruments, the biggest soundstage after the HD800S and a punch/impactful nature to enjoy Bass Drums, Hi-Hats and dynamic music with great enhanced live character and nice controlled bass.
To me it's a baby from Hifiman 1000V2 & ZMF Auteur in almost the best way possible. The material quality is amazing, the bag that looks like an ass
is very practical and the cables are the best i have ever seen at any given price point. Just wished it would have a silver accent instead of gold and standard 4 pin mini xlr connector and softer earpads.
