Sony MA900 vs Sony CD900st

post #1 of 31
Thread Starter 

i think i will buy Sony Ma900 or Cd900st.

 

as iam looking for the best sound for vocal music i found cd900st that is closed (someone said it was better than Q701 in mid, was going to buy it)

.

and then a few day ago i read about the Ma900, people said it was a better headphone than HD598 (that i really love), and thats an open headphone = more soundstage :)

 

so anyone have tried both ma900 and cd900 that can give me a comments of them ?

which have the best mid for vocal ?

 

and how the build on ma900 ? it seems kinda cheap :P

I have heard the cd900st and thought it was very good. a nice step up in clarity and bass from the 7506/V6. I imagine the MA900 to be better though.

do u think cd900st's mid is better than hd598 ?

I have the MA900, They are Awesome after I took out the resistors SONY put in there to compensate for high output impedance sources, Bass is tight and extended and very strong for a open headphone, plus the open design keeps my ears cool, the framing is magnesium and very strong but it looks "fragile, I guess Sony went function over form on this one because they are very light (190g ) for having 70mm drivers. I might be one of the first ones to do this mod on a brand new $300 headphones, but the risk was worth it.

So in conclusion I do recommend them but be prepared to do some modding if u have a good low impedance source, otherwise they are going to be crippled. Look up the MDR-F1, they did the same thing on them, people modded the resistors too and the difference is night and day.

I also intend to mod my MA900 soon. Is it the same procedeure as with the F1, The circuit is the same? 

 

BTW, the mod does make for a very noticeable improvement in the extention at both ends of the spectrum and thus very worth the time but it's not a night and day IME with the F1. Thanks for sharing though, You're indeed the first i've seen that mentions this wrt the MA900.

Quick drawing from memory

 

 

 

 

then I cut the trace where marked and removed the cable to bypass the 1.3 resistor

I copy/paste some jpg drawings but are not showing up

The cd900st isnt really like the HD598 at all, the Sony is much colder

@nemesis, You should attach it using the 'insert image' icon in the message toolbar.

This is the circuit

This is what I did to bypass the resistors

Showing in the drawings is just the Left Driver circuit, where the main cable "lands" as this is a left sided headphone, note that the right driver wires are just passing by here. You have then do the same on the right's circuit which is even more simple than this one.

How many ohms is the resistance you by-passed? Don't see the reason why you would short it since its used to limit max current, there is no voltage drop...

how about ma900 vs cd900 ?

post #13 of 31

IMO CD900st is more on the flat/monitoring side, while MA900 is a warmer, forgiving side

hmmm any idea which one is better for asian-pop, ballad, female voice music ?

post #15 of 31

I'd vote for the MA900, It has a slightly forward lower midrange that does help to highlight the vocals and all other relevant notes in that area, The midbass is also slightly raised to have the fun factor up a few nothes, Yet it is very nicely defined- I wouldn't call it muddy by any means.

 

@nemesis, Thanks for the illustarting, Looks like the same circuit iirc from the F1 indeed. well done.
