I broke the first pair trying to bypass the resistors.
Kept the foamy stuff but unfortunately tossed the frames in the bin...
the a5pro are excellent with the larger ear pads
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:
right driver is X25905151
left driver is X25905141
The Z7 just needs some damping to control the loose bass. I used sound damping foam sheet, the stick on kind for pc cases. I don't think it's worth it to swap in Z7 drivers, as you'd lose the glorious bass that they have and all told out the door, you could have just bought a set of Z7 to begin with. I own modded pairs of both the 900 and Z7.
I tried those Z7 a bunch of times. Using the matching Sony amp, they sounded much better with the "balanced" cable. That was a surprise. But maybe the amp was optimized to encourage people to buy the expensive balanced cable...
I'll revisit the Z7 page...
Only managed to demo the Z7 once on a local Jaben store... Build is amazing, but I only can do a 1 song demo as I need to go elsewhere, my impression of it is Good though.
Recently Jaben have the demo of the MDR Z1R, now THAT, Is the one I lush for...
