I have been able to try Dekoni Elite Hybrid pads (designated for Beyer DT series and AKG K200&500 series) with SE-M5's. The fit and comfort are excellent, and the dimensions are similar to stock, but with a slightly larger inside opening and no slant. This offers a very good seal, and actually tightens the sound a tad, matching Focals in clarity and offering a much nicer projection of the soundstage, separation of instruments in more complex recordings, and a more even extension into the bass without boominess (read: Elegia-killers). With IFI Micro iDSD BL (XBass on), the airiness, space positioning and clarity are breathtaking, especially for classical music and jazz. I think this is as far as a search for better pads takes me. These Dekoni pads are it.
On the pics you can see the Dekoni pads(mounted) and the Brainwavz XL pads (unmounted).
Looks good.
How bout some filthy shots of the sexy magnesium base?
