Ok, cool. I had no idea how much plastic vs Magnesium is used since I have not seen one in person. Plastic is easy to mod. I would love to buy two but I'm a minimum wage slave so I can't afford it. If I had the money to buy several I would even experiment with coating the driver C37 lacquer and such as well as the "Enable" mod (check out fullrange driver forums for more info). Such mods are pupular on high efficiency fullrange speaker drivers; Fostex, Lowther and such which is essentially what a headphone driver is, just smaller and nearfield.

The whole headphone frame is magnesium or some kinda of alloy. Is some part of the inside that is plastic. The SA5000 is one of those lightweight phones still feels extremely solid in your hands due to the alloy frame.

 "Magnesium is a highly flammable metal, but while it is easy to ignite when powdered or shaved into thin strips, it is difficult to ignite in mass or bulk.

  Once ignited, it is difficult to extinguish,"


Only pure magnesium is highly flammable, I doubt Sony would use pure magnesium to make headphone frames, there'd be thousands of expensive lawsuits. It's a magnesium alloy. cool.gif

Just was not sure of the concentration ~ if you check out old Porsche racing days from the 1970's ~ the old Fuchs

spoke mags would catch fire given enough brake heat, they would've been a mag/alloy too.

I finally found a pic online of the inside of the earcup and there is definitely a large area around the exterior of the grill and under the earpad that could use alot of damping material. Might be a large source of the irregularities in the higher frequencies which look like reflections causing cancellations and reinforcements (the large peaks and valleys in the frequency response). The bass response looks a bit odd too with a quick falloff and lack of bloom; venting out the rear behind the driver to let it breathe might help but I need to see it in person to see what can be done. (sort of like punching holes through the material covering the rear of Grado drivers which I have done with my SR80i's.)

I might be wrong...

I thought I read somewhere it was just the headband but you might be right, someone said they made it look like magnesium but it was in fact some effect sprayed on plastic... which leads me to another point; beware of fakes.

I've seen the frequency response and I don't believe it's accurate, regardless dampening always dulls the highs and let's everything else shine through.

Well I plan to get used to the overall sound before I do any mods. But the damping I was referring to shouldn't dull the highs really but prevent reflections from obscuring the highs. I don't want to dull the highs, I want it smooth as silk with gobs of detail, air and extension. Which is why I'm buying these headphones in the first place.

Subscribed. Can't wait for your first impressions. Gobs of detail, air and extension, yes and yes! Smooth as silk... depends on your source a bit as they are so revealing. Hopefully we can figure out a way to mod it to make it just smooooth as silk, and milk, and a baby's behind.

I'm strongly considering buying these. They have a very unique appearance, and impressions suggest that they sound very clear and good, and it looks like they can be had for only $350 or so brand new? Yes please.

I would suggest they sound very clear and bad.

 

$350 is painful.

 

Won't hurt to audition them I suppose. With your D5000s you've had plenty of the bottom four octaves anyway.  ;o)

post #41 of 580

Dude, you're trolling at this point!

post #42 of 580

I don't think so. I'm passionate. I think they're incredibly overpriced at $350 (which is about what I paid by the way). You can do better in the same sonic vein for less than half the price. I hear similar comments about the M50 pretty often. I think they have quite serious shortcomings. However, as long as the place they're ordered from has a solid return policy, there's no harm.

post #43 of 580

Man, I just couldn't disagree with you more. I think they are a STEAL at that price for how well they do certain things. I consider it a "specialty" phone, sort of in its own class of sound. And that specialty sound doesn't jibe with you, we get it.

As long as someone stumbling on the thread knows what they're getting into.

 

You're absolutely right about the "specialty" tag. But someone else described them as "basshead" cans in this thread. That's like saying my Civic Si is a "torque monster" because if you're careful with the shifting it has adequate torque to get around town.

 

It'll be interesting for him either way, why not try out different signatures (assuming good return policy)? Get some variety. And draw his own conclusions...

I do think the SA5000 is Basshead territory because of the fantastic control. Trust me, I can definitely get them vibrating on my head, without a doubt.

 

And your argument is fair enough.
