So I've been reading and comparing reviews on the ath-AD900x and the ath-A900x. I decided to go with the A900x mainly because I don't think the AD900x will have enough bass for me, and I've reading that the A900x has a decent and wide enough soundstage for a closed back. We will see, and hopefully this will be my last "headphone" in a long while. I'm not crazy about headphones, and I never listen to my M-50. I do enjoy my S500 and FA-011. And the Creative Live (but I rarely pull it out. Most of my time will be spent with earphones, but I wanted a big clear sounding headphone for occasional movie watching and to not have something stuck inside of my ears all the time. I'm reading that A900x is about on par with the AD900x in clarity. And I found them new in the USA for a fantastic price. I should see it next week. I'll let you know how it works out for me.
Cool! You should also get the ad900x's to compare, and then sell them to sfwalcer if you don't like 'em lol.
I consider myself almost to be a bass-head, simply because I really love the bass in my s500's, and also I love the bass of my bassier iem's (ie mh1c's (boomy at times), mt300's (troll on sf!) and my gr07be's (beautiful bass)). Having said that, I really don't find the bass to be lacking at all with the ad900x's - especially when paired up with the E12 v1 and it's subtle sub-bass boost. I think the main reason is because the sound is so beautiful and balanced across the entire spectrum that I am not sure that I would want it changed at all. Also, I can crank it up loud if I want without any area sounding abusive or fatiguing. Just lovely.
Having said that, occasionally I want to get my bass-on, and I am being persuaded that the WS99's are just a bit awesome. It is hard for me not to imagine that the ad900x and ws99 wouldn't be the perfect pair.
But enough about me and back to your ad900s... I hope you like them, and I am really looking forward to your impressions :)
