I changed out the cotton stuffing in the rear of the 840 pads with rolled up strips of Vinyl, what I found was that stuffing with cotton really bulked it out, and the area inside the pads was greatly reduced. Rolling up Vinyl and stuffing it into the rear of the pads, really kinda flattens it out also, and now the stuffing is neatly tucked in behind the rim of the pads and not bulking out like before, this has worked out very nicely.
Conclusion.
Comfort
Soundstage
Imaging
Detail
All improved greatly.
Working on a perferated Vynil cover for the earside of the driver, lets see if it will improve any reflections or simply muffle the sound or reduce detail as I experience before with other earside driver coverings.
Noob cable question
How many of these cables do I need to recable the T50RP? 1,2 or 4? Each cable has 2 strands on the inside.
