Nice write-up. The 3D is Amazing with some headphones.
I liked the amp at first, but after three months I appreciate it a Lot more.
Glad it hear it’s a great match with your Arya’s! 
Thanks for the wonderful review. Mind if I pass this along to the team?
Sure thing!
can the tubes be swapped out for one’s known to be warmer?
Yes, they can be but it’s a pretty extensive process that I think voids your warranty.
Let me double-check with the team tomorrow morning!

voids warranty? what if hey burn out? silly policy being tubes are meant to be rolled!
Hey @sebastien_chiu_iFi, were you ever able to get an answer about tube rolling? Have to agree with @Marzipan here - they’re made to be rolled! 
Yes, it voids your warranty.
If you trust yourself enough, I would not shy away from doing it - it’s a great way to get a sound you may like better (or is subjectively better depending on your taste)!
