So I tried the hair roller mod tonight (with current mods, ZMF Ori pads, 120hours burn in, grill mod) and I feel like it makes them borderline too bass-oriented. The bass is quality but it was nearly fatiguing given the impact and quantity. It definitely was stealing a bit of the show away from the rest of the spectrum. Makes me wonder what the perforated sheepskin Ori pads with the hair rollers might achieve though. As of now I took them out and definitely enjoy them more this way. Plenty satisfied with the low end, especially the balance it achieves with out the additional mod (hair rollers.) It does make them a tad more intimate with just the Ori’s although any positive soundstage/imaging changes with the rollers were somewhat lost to the bass impact/amount increase. But for those looking to get more bass...ZMF Ori pads + hair roller mod won’t leave you wanting for more low end.
