I got a cheap litz cable (80£) from CustomCans and happy with it, I don't know but I feel it increases the clarity a slight bit more compared to the stock cable which you may or may not like with the SE. https://customcans.co.uk/shop/product/balanced-denon-headphones-cable/

Like my LCD-X (2021) with the Mojo 2, I find it has more dynamic slam than HE1000 SE, it sounds better for low dynamic range music (for example many old rock and heavy metal recordings), SE resolves more though and trumps the LCD-X in most parameters if the recording is good.

I said the audio micro-usb port not the charging port 🙂

Just noticed (after couple of hours) I had plugged in the charger to the audio micro-usb port, can it potentially damage the Mojo 2 or there is some built in protection to mitigate such scenarios.

I got this one from aliexpress, quite good for the price actually, the webpage says its made for dual band headphones like HE1K / Arya so can be rested on the metal beam to protect the leather headband. https://www.aliexpress.us/item/3256803636517547.html

Yes.

@Andykong Is there any plan to introduce RU7 like 1-Bit Ladder DACs in future iteration of N3 series.

Hopefully someone will post a 3-way comparison of Cosmo with SJY Horizon and Arya Stealth as they are in similar price brackets.

OTL tube amps are generally not good pairing with low impedence h/p like Focal and Audeze, better try hybrid tube amps or OTC (more expensive)

Surprisingly HE1000 / Arya headband is not in the store, you can try sending an email to customerservice@hifiman.com, I will be surprised if they don't sell a replacement headband for such a highend headphone.

The SE is still 2k, I guess you meant 3.5K.

How is the dt-880 (600ohm) with ta-66.

I would choose either the Focal Utopia or ZMF Atrium (prefer this one), HEK series when I want to be bombarded with details and technicalities, Atrium for just chliing out,

I have been listening to the LCD-X+Mojo2 quite a bit recently, my impression has changed!!! I increased the voume to green/cyan region, maybe my usual listening volume (orange/yellow) didnt bring out the dynamics that much, granted very rarely a slight bit treble hotness appear here and there...

Seeing couple of good impressions of SJY Horizon (one said it easily competes in the 2k range) so any comparison with Arya Stealth so far, both are near about same price.
