I really want the DT990. REALLY bad now... But, I am also REALLY struggling about the decision to go with the 250ohm instead of the 600ohm. At this point, I just don't know if I can get away with spending $250 on an amp. I have a wife and a little girl - there exist other priorities than a $250 amp. And $250 is the max I foresee spending on it - I can't justify more (preferably $150, even used).
With that said... someone mentioned that the FiiO E5 would drive the DT990/250 decently to the point that I could listen to them with enjoyment. And please don't laugh, but would the FiiO with the 600ohm just be useless (same ? for the 250ohm)?
Can someone explain what it will sound like exactly if:
1. I listen to either of the DT990 (250 or 600ohm) without amping via my Sprint EVO 4G phone and Gateway laptop?
2. I listen to either of the DT990 (250 or 600ohm) with the FiiO E5 via my Sprint EVO 4G phone and Gateway laptop?
3. I listen to either of them with a dedicated amp/dac?
Also, while I'm at it... can you recommend the least expensive amp/dac with crossfeed that is portable that offers great sound and a rechargeable internal battery? Probably a Meier Move3 I suspect... but what else? Cheaper the better please! Also, if it is inexpensive and lacks features, but will drive either headphone (be specific about which ohm model) adequately, let me know please.
P.S. I'm really wanting a pair of these... if I have to buy them, live with less-than-optimal sound for a little bit, than so-be-it, just let me know what I'm in for that's all. And given that scenario, would it be best to just get the 600ohm?
