I've noticed I tend to only buy things that I like :O all of my reviews r 5 stars I think... maybe not the K550 but >.> I need to start buying some crappier headphones lol
more on topic I got the AD900x today and... DAMN it's nice for EDM, it's very much like a balanced Dt 990 [the mids are the same as the dt 990 sadly and but it has slighty deeper wollier bass] ... a nice can for sure!
I liked the AD900x, but did not like the $/Performance.
The AD1000x price increase makes the AD900x a more sensible choice though..
I have to ask, what is your source? The AD900x has much less fuller and weaker low end presence than the DT990 lol. Drums in general sound like thumps on the AD900x, whereas on the DT990, they have more texture and detail. Maybe the AD900x has more subbass impact, but sounds hollow and anemic when A/B imo.
I agree, they do sound more balanced. But the mids?? THE MIDS?!? The only reason I considered keeping the AD900x was for the mids, otherwise I would have sticked to the MA900 or DT990 longer. I love the Audio-Technica sound, though I wish they would sound better for American/Euro Rock Genres. They color the instruments too much, this goes for the whole AT line in general. Beyerdynamic and Sennheiser seem to be more accurate in this respect.
For me the AD900x was a less warm, more detailed, and open version of the A900x. Its been awhile but I know that either of the two had edgier treble. Probably the AD900x, because of the air-ier sig.
AD900x sounds more transparent and detailed than the A900x, but I think its more of the signature than technicalities. So for twice the price (or more if you buy them new today), I ended up selling the AD900x, and am waiting for a bargain AD1000x/AD2000x. Holding out with the A900x makes things easier, some songs sound magical on an AT headphone.
DT880 Pro + Aune T1 + Voshkod Rocket Tube is my new price/performance winner. They sound more accurate, and aren't as analytical with the tube as a buffer. The voshkod flattens the v-shape, I still would like the mids to have more emphasis however. But all in all, its the combination that I feel that nothing under twice the $ will be worth purchasing.
DT 880 Pro = $210 new, Aune T1 = $130 new, Voshkod = $11 NOS.
