I have tried the brass tips of the ED9, but I can't get a good sound out of it, it sounded so thin and lifeless, even though I have changed the tips from stock to comply. I went back to the gold tips and removed the grills and foam, now it became a lot better.

Something is either wrong or you aren't getting a proper seal. The ED9 IS Bright BUT it is anything but thin. It has ample, (bordering on too much), Bass.
Personally, I'm getting the Best sound from Auvio Medium Tips available from Radio Shack. These are similar to a Sony Hybrid only heavier / softer Material and a VERY Wide Bore. I tried the Larges but they were uncomfortable after a while with the deep insertion of the ED9's. Went down a size and all is well. Using the Brass nozzles.
