I did a video 2 years ago in this post which is gone now. I can do another showing the eq and amp and track. My ma900 do not distort.  There must be a batch or a period when something changed? I can listen to 2pac just fine. Not like a closed back of course but in impact, accuracy and ability to be elevated.
 
I would EQ sub-bass 25-55Hz and not so much the 80-120 area as it has a bass lens and is designed to keep control of the diaphragm.  I sold my T1 because it did distort under EQ and amp but the ma900 does not.

 
not sure, can there be a batch that can distort more, than the others?
 
wondering a bit as some of the elements, are a bit prone to distort
 
what are your terms on how the SQ is, considering distortion, or not a pure signal, om the 900?
 
may be that there is more a SQ rather, still i find it a bit distorted in some elements, especially when Tony mentioned it 
will probably get better
 
what are your burn-in time, is there any that you feel is necessary, if there are some distortion or driver compression, that doesnt work flawlessly?

Are you using an EQ and if so where and how much? What amp?
 
I think the SQ is fantastic. Analogue like warmth with no harsh treble. sub-bass can be rolled but I EQ that part and nothing else. Sound stage is peerless

Agree, its a very competent driver and respond well with some EQ on its lower frequencies IMO

The 900 just dont handle compressed music very well from some reason, you are less likely to come across distortion when hearing records from the 90's and earlier.
 
At 1985 those could have been:

no eq and if i want a high volume, JDS Labs Element
 
sometimes a bit lower on the 60 - 65 hz, what ive tried, may be that i use to high volume
 
it has good sound at lower volumes, that satisfies, still it get some not so very pleasurable small distortions in the SQ clean signal at higher volumes

Hello people Just got a quick question here.. What are the replacement pad options for the MA-900 in term of comfort and sq ? Are there any pads which are thicker than the stock and do not let your ears touch the drivers?

I'm using the brainwavz HM5 pleather pads on mine

Any of the pads that fit the size of teh DT 990/880/770 will probably fit the ma900. Look for a thicker pad. Here's what I used. The cover over the ma900 driver itches my ears so those were removed as well. It's easy to do.

Does it alter the frequency response? Did you also remove the cloth in the middle of the dekoni pads?

On my experience with the brainwavz HM5 pads :
 
I removed the cloth in the middle of the HM5 pads, somewhat regret it
 
Sound became a tiny bit more shrilly, like there are more treble peaks from the MA900, less warm than stock pads.
 
Didn't try the dekoni pads though, so might or might not be the same results on the the dekoni

yea thanks i will see how it goes

You sure it fits? I tried to fit my HM5 hybrid that i have lying around, and it just Won't Fit.. It's oval and the length just barely exceed the cups circumferences.. Unless I try stretching it till near its breaking point i just can't fit it on.

Yea I removed it. It was never made to be there in the first place (in context of the 900) technically so it should not affect the sound since it wasn't supposed to be there. I also removed the thick ole driver cover, the super scratchy mesh over the driver. If you follow that link you will see. The dekoni memory foam pads are more square so they actually seal better. I don't think they affect the freq response, not sure they could regardless. But the mesh cover over the driver definitely soaks up some sound as it is a thick mesh lined with foam. The actual driver already has acoustic paper on it to massage the sound and I left that intact. I would not put it back to stock at this point, even though it only takes a minute to redo. I like the sound the way it is.

Has anyone tried using the MDR-Z7 drivers in the MA900 open frame?
 
I had owned two sets of the MA900 and am listening to them now. They are very durable and still sound good.
 
The MDR-Z7 seems to have a fantastic driver and excellent clarity but the closed form factor and perhaps an odd bass port made the low end sound discombubulated every time I tried them.
 
Sony sells the drivers for about $100 each and I think the part numbers follow:
 
https://docs.sony.com/release/MDSM/989605201_sm.pdf
right driver is X25905151
left driver is X25905141

That's an interesting question.. I wonder whether anyone'd be willing to try it out.
What happen to the 1st pair?
