Hey everyone! Thanks for taking the time to read this. Atm I own the Audio-technica ATH-M40x, which I've been happy with since I got them. And I have 1More triple driver IEMS for outside. However I've been thinking about buying some open headphones, that would also be at least a level above the ones I have now. I've been looking around and the ones that pop out the most to me are the Philips Fidelio X2s and the AKG K712pros. Now the thing that makes it hard for me to choose between these two is that I would have to buy an amp for the AKGs, because from what I've read they really need the power if you wanna get the most out of them. The recommended amps that I've been seeing are also quite expensive. And there's a bit less choice for me as well seeing as I live in EU. So it would be easier and cheaper for me to get the X2s, but I'm still doubtful as I don't want to get the X2s and end up thinking, hmm, maybe I could still use an upgrade of these. Maybe it just makes sense to spend more and get a decent amp and the AKGs instead of stay below the level where you don't need an amp. So I wonder if there are any amp recommendations I can get that I haven't seen elsewhere, or if I should maybe just stick to the easier route. My max budget atm for an amp(/dac) would be around 100eu. (and I don't have any experience with them, besides the research that I've done) Before I forget, I will mostly be using these headphones for music ((progressive) metal, DnB). And a bit for gaming as well, but that has less priority to me than music. If I've missed any info or if there's any other questions, please let me know. Thanks!
