I've been off of head-fi for many years, but I'm happy to be back.
The MA900's have been my first non-iem headphone purchase in 5 years and so far I'm enjoying them. The last pair of headphones I owned was the Grado SR325is and I feel like these sound a lot like them (but this was about 6-7 years ago). To my ears, they sound very bright and I'm hoping that with time they mellow out a little bit. It seems that they also have a lot less, "attack" than the old Grados and actually seems to suit me.
So far these are miles above the 325i's, mostly because they are so damn comfortable and I can listen to them for more than 25 minutes without my ears aching (from how uncomfortable Grados are and how bright the headphones sounded).
Coming from IEM listening for the past 5-6 years (triple fi 10s, as well as my speaker set up) it's really nice to have some headphones that sound very open.
Over all, pretty happy with these, but I really hope that over the next few weeks/months that they mellow out a little as far as the highs are concerned.
-----Is anyone else using a tube amp? If so, what tubes would you recommend to maybe curb those highs?
So happy to be back, I've told my wallet that it won't have any problems because I'm not buying anything else.
Seriously, I'm not buying anything else, just these headphones.
