What I find amazing is that you can wear the LCD2C for three hours.
I'll be honest with you, I am a fan of Audeze in general, I also have LCD-2C, and I will also be making a review on it sometime later.
I really think Arya is in another level of comfort entirely, man LCD-2X is heavy. Comfort wise, HIFIMAN knows their stuff, Audeze are heavy. this being said, I love the pads of both, both are really comfy.
HiFiMan warranty is also officially non-transferable, and just look at the response from the official representative above. It can be transferable if you can provide a purchase order. This is the case with most manufacturers including ZMF. Small factories will do even more to help as they realise, that's the way they can grow.
HEKV2 prices drop to 50% on the secondhand market because that's exactly the cost of driver replacement. Audeze replaces LCD-X drivers for $600. Pretty much 50% of the new price (creator edition). You always take risk by buying secondhand.
400 euros is around 30% of the Atticus price. Still not bad compared to the other two brands.
From experience, someone bought a HIFIMAN Ananda in Romania, and had receipt, but it was on a totally different name from USA, basically he bought Ananda from USA, from another name, but HIFIMAN still accepted his warranty and is currently solving it.
I am working my way to my Jade II Review and when it is ready, I hope my friend with his Ananda will also have solved his warranty, because I want to clear that up, he had good experience with HIFIMAN. For the record, I do not have Ananda myself at this moment, it is just a friend who does...
I wouldn't stress it too much, as long as you have the paperwork, HIFIMAN are good guys as far as the actual experience goes, just take care to have the actual paperwork of the purchase to get the warranty. I mean it, I have seen them fixing stuff, as long as the papers were in order.
