It is quite amazing how well the Paradox T50RPs measure compared to something as expensive as the SR-009.

Have you had a chance to hear them - the Paradox?

They are due to be delivered today!!!

I received my pair of Paradox's from Luis yesterday and posted my initial comments at head-fi (post #5321): http://www.head-fi.org/t/452404/just-listened-to-some-fostex-t50rps-today-wow/5220#post_7936071.

Purrin / LFF: If you'd like, I can "re-enter" these initial opinions as a new topic under headphones or a "review" section if you create one.

I always get paranoid. To me, the SR-009 sound much better. Could be due to the open design vs. the closed and sealed design of the Paradox....who knows.  ???

Purrin has heard them btw....

Hey marv,

I am considering giving a second shot to acoustic simulation of the sr009. Your measurement on baffle plate would be of tremendous help to calibrate the model. Would you be keen to join the project?

That means I need to know your dirty little secrets though (equalization curved, test rig acoustic conditions). Obviously, since you want to keep the secret sauce to yourself, I would present simulation results with equalization applied and not divulge the baffling conditions.

Care to help?

Adding measurements taken at the SD Coronado Meet.

Frequency Response:



CSD right:



CSD left:



Relatively noisy meet conditions not optimal for distortion measurements.

These are no bass monsters. Relatively clean CSDs.

Amplifier was SRM-252. I believe Marv used a DIY-T2.

I'm certainly not going to argue about the 009 not being a bass monster, but this graph seems a bit far from what I'm hearing...

Yeah, well, you know, that's just, like, your opinion, man.

Could be seal Ship. I've heard some people actually use rubber bands to press the Stax against the pads. Dunno.

Are you going to post the Lambda measurements?
