Hey new member here, Just thought id throw in my quick and dirty impressions. Nothing very technical - just overall impressions vs other headphones i currently own. Those being Arya stealth's and the hedd D1. Been a member over on head-fi since 2007, generally been a huge IEM guy, owning dozens of sets over the years and only really recently decided it was time to let go of the IEM hobby, get rid of the collection and purchase a single set of headphones to get me by... those were the arya stealth, curiosity got the better of me and 1 turned into 2 with the D1's and then 2 turned into 3 and here we are with the 480 pro's. I use an ibasso pb6 amp for them all out of a little cayin ru3, nothing crazy but more that satisfactory. I love the Pb6, this thing is chefs kiss, never been tempted by anything else since getting it such is the job it does with no fuss and thats unusual for me as i have the really bad habit like many of us i guess of looking for more all the time.
Anyway my favourite headphone right now is the D1, followed by the 480 pro then the arya stealths... i shed a tear thinking about spending £1500 on those things, they are good but not £1500 good and ofcourse hifiman thought the same also eventually.
So why the D1's over the 480's you might ask, really it just comes down to general hardware capability i think, i get the very real sense using the D1's that the headphones are extremely capable, if i EQ in a bass shelf it responds perfectly, it likes to be played with and can take it with ease... a real sense of having quality components built to do what you decide to do rather than built to do what the manufacturer intended and only that alone. I dont know if that makes sense because im not the kind of person with massive technical knowledge on these things but i feel like for as good as the sound is from the 480's - it is giving all it can give from those 38mm drivers, I do hear a little bit of warbling in vocals when really heavy bass is playing (admittedly at really high volume, because im an idiot), but its something i dont get from the D1's which really do just seem to take it and my ears would clearly fail before they do.
When it comes to the actual sound quality itself rather than just hardware performance i have to say the 480's are incredible, i really really enjoy the tonal balance, everything comes through clean, vocals are right there and the mids in general show excellent timbre, it all just sounds right and i think the treble is smooth and so easy to listen to. I think the D1's are better still in the mids but i prefer the high end of the 480 for longer listening sessions, i also prefer the bass quality and presentation of the D1, its not nearly as forward in its presentation but yeh those drivers just respond so well down low even if its clearly not tuned with emphasis in that region. Adding a shelf there just transforms everything.
In comparison to the arya stealths, truth is they have not been on my head in weeks. The highs are too much for me but again its a headphone that i really like how the bass presents, well extended and if you moderately shelf it and give it the voltage it likes it will rattle your cheeks, there is lots of texture but its easy to find the point in which the little available excursion is found and that dissapoints me. The 480's by comparison present bass far more in line with what i would get from IEM's, they feel small by comparison and it comes across that way even if the bass is much more forward in the tuning and presentation.
Anyway, good to see everybody elses experiences, seems like a great community of folks.
