And that creates the famous Stax fart sound.
Comparing your new phones with your prior version, which one sounds louder?
Last time I listened to SR007's, they did have a fair bit more noise to the slam than my headphones do with the flat paint I use (which is nearly silent), although nothing like this glossy paint. I could see the surface of typical copper clad being a lot more textured than glossy paint, especially if Stax gives it a sanded finish. Who knows, not really worth debating about. I've had mixed results with exposed copper, great results with flat paint, and disastrous results with glossy paint. Take from it what you will.
Indeed, thanks for the painting idea. If I'd just used the same paint as last time, I wouldn't have had these problems!
The new headphones at 900V bias sound about the same volume as the old headphones at their 580V bias (I don't like to drive them any higher than that, I've heard pops and crackles in the 700V range).Although I only really listen to the new ones since they sound vastly better in basically every regard.
I would have expected the difference in efficiency to be (0.5/0.8)^2, but it's a little more favorable than that. Likely because of the larger driver area.
Should have everything at the NY meet on Saturday.
