I feel asleep watching X-men "The Last Stand" ...the end woke me up...
I have modded the SR60's and the SR125's the original versions and i can't tell the difference between them when equally modded. The SR60's are the ones that got the wood shells I think somewhere on here I wrote they were 125's...OOps!! The only way for me to tell is the cord on the 60's is mini plug and the 125's is 1/4".
When I first started with this journey like two days after I got my first pair and realized that these were special I somehow started talking to a guy who works for Grado and he said awhile back a bunch of us audiofile types got together on a Sunday afternoon and tried all the models starting with the first ones on up and pretty much everyone who was in attendance said the entry level Grados were fine and the biggest jump in performance came with the 325"s. I asked him straight up as a disabled retired guy which model should I save for- if I had the money I'd buy the best ones but I don't- so he said off the record enjoy the 60's and save for 325's next.
Then I started modding these and all bets were off. I have some Ultrasone Hfi-700's (Alienware Branded OZMA version) and they were always my reference cans and as I made changes to the Grados I'd compare, they always won until I did a bunch of mods and then Dynamat. Then they were passed by my modded cans I paid $45 for.
I did...linen removed, large ear pads, removed the shells from the tray and did 4 holes (now 10) and did Dynamat and I was drooling, zooming past the Ultrasone's without any other shell mods or screen thing yet--nothing and then the health crap started up but before I really got slammed I received a pair of 125's and they were way too bright!! So I quickly modded them and went one step further with the thin foam at the end of the chamber and then ended up with those in the hospital and enjoyed them immensely, and everyone that heard them remarked that they were the best headphone they had ever heard, "I didn't know headphones could sound that good" was a comment a young physical therapist made who know---he thought--his audio gear, he was floored.
Then I got home and the shells arrived and I took the foam from the 125's to use in the 60's with the wood shell because Bill had installed the mesh for me and WOW!!!
The only material I've tried in the end under the mesh is the thin foam I stole off some Sony's I had and tried to mod. I haven't tried anything else but I think I'm the only one using them that way and with the EVS things in place I'm golden and I think the only one using them now.
The original way I did the foam would be a great way to try other materials etc..on the cheap...use the plastic if you can't swing the wood and do like I did...I took the plastic screen off in one piece with the logo button in place and used the plastic to reinforce the thin foam and hold it in place..
I used the screen pictured above right behind the thin foam with the lgo button facing outward which pushed the foam out a little bit making the nice rounded look...the bass tightened up, sounded more like closed cans nice deep bass, not boomy or thin and the open sound of Grado's we all love was there also and the dynamat was the big equalizer smothhing out any spikes and the foam/plastic grill let some sound waves through but cut back on the thin sound you get sometimes with headphones. The plastic screen was the only material I used and the thin foam also and I wrote in the thread earlier you could go to town trying different combinations of materials for the screen and the thin foam insert...endless possibilities.
So enter the Cocobolo shells..Bill put a notch in mine for the cable because I have no drill, no soldering iron and basically no feeling in my hands so Bill hooked me up and put some mesh screen in mine--the exact color and grade I would have gotten by the way(Thanks Bill)- and because of the nothc Bill made a little lip around the inside of the shell to keep the driver tray from going any further into the shell crimping the cable and in doing so he gave me a much bigger chamber to play with. With all mods including the shells but without anything behind the mesh they sound a bit bright sometimes and sometimes they were perfect--I like perfect all the time so I pulled the 125's apart took out the foam rebent the nesh a little and tuck the foam in and closed it all up to find myself with tears of joy because my new friend Bill had so graciously and quietly building these shells for me while I was in the hospital and when I got out these welcomed me home and back into action..so the foam is in, the EVS is in, all temporary with tape as solder..LOL....I did 10 holes around the out side. I did not put any lining inside the shells..the foam is just under the screen only so the chamber resonates and adds to the sound with that little bit of foam cutting out the unwanted frquencies...
In short---I love these cans, they will be handled with care and with me until the end of my time...this was more than sending some wood shells to a guy, there was serious concern, serious support, serious generosity, and dare I say Love in these shells...Bill gave a minute of 3 for me and my situation, my brother in Portland and sister out side of Phila. never called once, no body visited me except for some friends from audiocircle and my roomate.
This thread in many ways has keep me going, thinking about what to try next etc...i took these back to the Hospital Thursday when I wen for a Dr's appt and a crowd gathered around to see the headphones I'd been boring them with for the past 2.5 weeks....LOL...
Mod on!!!! I will...I still have some 125's sitting around from before I went nuts and took them apart for the wood shells.....Fun Fun!!!
