What are you driving with your srd7 the sound may depend on the quality and the power of the amp? The cause of the sr-x modding is the original sr-x pro is very rare. To get pro driver is hard because the source for example the sr-gamma pro is rare too. And the diy game factor you can ruin everithing easily. The pro sr-x is better first in the bass but not only, but I never thought it will be my main rig. This is the Omega beleivers' thread and some of sr-009 converts' I only getting the itches now to try an sr-007 mk1 I have (cheaper) stax phones for two decades, then the sr-007 was cheaper too unfortunately. An other possibilites , If you are good in electronics you may build a normal bias circuit to your 323 but this must not be your first project because of the high voltage.

The less dangerous is cutting the stiches on the headband I think. Or remove one of the side plates (with the L or R on it) it is glued to the black block and then loosen the screws under it and you can pull out the pole I think but I never tried.

I had a normal bias sr-x mk3 too for years not much used and I always thought I would buy a gamma pro and convert it to a pro. A few months ago I bought the gamma it was almost as new except the headband dyeing (as spritzer usually tells), but with a serious imbalance. I let the bias on for a night but it did not get better even worse so I set it aside I thought I would inspect the holes on the diaphragm later. After a few days I tried again and the imbalance was smaller than I remembered then it got worse again. I thought it is not the holes or the coating but some contact problem. So I took apart the left driver the diaphragm was intact and I think the cause was the bias contact on the metal ring of the diaphragm I bent it a bit and the gamma lived again. This is the first thing why I wanted to tell this sometimes it is so easy. Then I had not the heart butchering this beautiful little gamma so set it aside again. Finally a few days ago I made the transplantation and the patient lives and sings so the ending is happy. Of course I have read all the posts about the transplantation on head-case and head-fi, googled a lot. I found the post from spritzer how "seal the baffle" with blue tack and it works the sr-x got better yet not only in the bass but at all. BUT !!! do not do this mod if you want to take apart your sr-x again because you can not. The blue tack is bloody strong maybe I used a bit more than needed. I almost ruined the headphones because I wanted to check something on the driver. This was the second thing I think it is worth telling.

changed V2 to V3 too

I updated my list to 2x V2 amp + 2x V3 amp + 1x GR HV PS + 2x Single FAT HV PS

One set with dual psu
