Headphoneus Supremus
I would appreciate recommendations for both dance music as well as 'spacious' music, like ambient, minimal and soundtracks, like Tron, Inception, Dark Knight.
PRO900 or 2900.
No but seriously, the 2900 are probably what I'd pick between the two; both are very good, and if the 2900 don't come down in price soon I'll tell you to get the 900 (it's not that the 2900 are overpriced at full MSRP, it's that the 900 are often available for about half that, and basically just as good).
But if you want to move away from Ultrasone, there's other headphones to be considered, that will be just as enjoyable (albeit quite different) imho:
Discontinued:
- Sony MDR-SA5000
- Denon AH-D2000
- Sony MDR-F1*
Still in production afaik:
- Kenwood KH-K1000
- Koss MV1*
- AKG K701*
Not all of these are bass-heavy (most of them aren't), but I enjoy them all quite a bit with the kind of music you're talking about (especially ambient and/or electronica). The Sonys will probably have the least bass of all mentioned, but are still (imho) fantastic with something like the Tron OST or AFX thanks to their fast, light, and punchy presentation; the Denon and Kenwood will give you a smoother presentation (Kenwood being smoother than Denon) than the Ultrasones, with similar amounts of bass (Kenwood go lower but aren't as punchy). The Koss and AKG are kind of odd-balls on the list; the Koss are fairly bright and lively sounding, with decent bass extension but not tons of slam, while the AKG are fairly leveled-out overall, but offer a very spacious and airy presentation (and are relatively fast) that lends itself to a lot of things beyond going "boom boom boom."
I'm not sure how I'd rank all of the above plus the Ultrasones overall, even with additional bounding - I think the PRO2900 do a fantastic job, but I also think the others can be just as enjoyable. It really becomes preferential (and potentially limited by budget and availability as well). Basically you need to determine if you like a very punchy/crunchy sound, or a very smooth/airy sound, and then how important gobs of bass are to your enjoyment of music. And then go from there.
I'd basically organize them like this:
Punchy + Bass:
PRO900
PRO2900
Punchy + Not A Lot of Bass:
MV1
SA5000
Smooth + Bass:
D2000
K1000
Smooth + Not A Lot of Bass:
F1
K701
The ones with * after them need some thought given to what they're being plugged into as well, and the K701 and SA5000 only come with 1/4" terminations (stock).
