NIce! That should help a lot, very smart. 

    I had the same feeling after listening to the cure's bloodflowers with my 650's!

Nice man, good luck on your build. When soldering the wire to the drivers try to do it as fast as possible to not damage the drivers. Also try to make the wire contact the metal pad directly instead of using solder as a bridge. This should improve the sound quality :)

  Yeah I made them out an SR-80i headset. Everything else I bought from a place called qables on the internet (silver wire, y-splitter, neutrik connector, and the mylar sleeve). They have good products and prices. The hardest thing is getting a good finish!

Yes all I used was hole-saws on a mill and a lot of sanding  They are made out mahogany that I found by visiting a local furniture maker. He gave it to me for 5 dollars! The grills are made out of a strainer I found in my kitchen jeje

    Just finished my first grado headphones!

You gotta love the hd-650's!

You can find some pretty good deals for HD 650's on ebay. I bought mine used "like new" for a little over $300 US, two weeks ago

Hey Fred beautiful work on the boards! Can you tell me the dimensions they have?
