Thanks for the reply
Currently I use three headphones:
- At home: AKG K702 (with bass mod)
- when commuting: Sennheiser HD25 Aluminium -> "upper mids and treble are slightly forward"
- for sports: DUNU DN-1000 -> "The top end of the DN-1000 is bright and crisp, and again rather typical of a TWFK-based earphone."
I have two rooms with Klipsch loudspeakers (horn-loaded).
Considering these choices I
guess I am not treble sensitive, but I am not sure.
Yeah, the AKG 702 can be a bit nasty in the upper mids/low treble- the Elear have a bit of a spiked response in a similar area. If you're OK with the 702, then maybe the Elear won't be like Kryptonite to you. I haven't heard the "bass mod" that you mention, though, admittedly.
Anyway, the Elear is a far better headphone in terms of most technicalities, and a lot more resolving, though I am not sure about sound stage. However, it'd still be a hefty upgrade in general. (The Jotunheim has a very wide but shallow stage, for what it's worth)
You probably won't have an issue, though maybe get the Elears from somewhere with easy returns just in case? Then there's no risk. As for the Jotunheim, I'm certainly in no position to talk you out of that- you'd be hard-pressed to find a better value solid state amp right now, brilliant bang for your buck. It'll probably stay on your desk long after you add a fancy tube amp, too. It's a very decent bit of kit.
That said, there's a lot to recommend just throwing some HD650 on the Jotunheim, via a balanced cable. Given the price differential, the Elear doesn't leave them in the dust quite as much as people might hope. It's a slightly different flavour, a touch dark, but the Jot really does bulldoze through a lot of the sleepiness of the HD650, producing a surprisingly nicely-controlled sound.
