I've just caught on to some of the Addicted to Audio Focal deals we're getting here in Australia now that AtA has lost their distribution rights. I've spotted the Focal Celestee and Elegia for 600 AUD (~380 USD / 360 EUR) and 330 AUD (~ 210 USD / 200 EUR) respectively, both prices tax inclusive. These prices seem like they'll probably never happen again in Australia for such a well regarded brand, so I'm wondering whether I should take my chances. However, this runout price is also only being offered with a one year warranty.

I'm currently running a pair of Beyerdynamic DT 700 Pro Xs, and I've really enjoyed them so far. They are my first pair of studio headphones as opposed to a gaming headset and I've found them to be very enjoyable for what I listen to, which is mostly modern rap, hip-hop and industrial. I feel like my listening style is more suited towards closed backs, I've given the DT 900 Pro X a go and while the wider soundstage was nice on music that utilises it, I didn't find much of what I listened to really made good use of it, and the lack of bass extension was a little bit disappointing.

I guess the only thing I'm really worried about is whether the music I listen to will really benefit from nicer headphones. The Focals are obviously objectively better than my current set, but will I actually be able to hear that with the style of music I listen to? While the obvious answer is to give them a try, there's nowhere in my city where that's really possible. Additionally, is the one year warranty going to be a concern or are Focals generally pretty well built?

At the moment I don't have any "real" DAC, I run my DT 700s out of an Apple dongle (praise be). Would these headphones benefit from a "proper" DAC? Obviously an amp would be overkill with their low impedence.

Happy to provide any more info if it helps, thanks for any help :)
