pro's , con's ?? and any advice on how to proceed ?

 

If you're set on gluing them, try getting glue in a spray can and spray very lightly only the cloth.

 

Gluing on cloths is tricky at best with any other kind of liquid glue and WILL make a mess and not form a consistent seal.

Inconsistent gluing will potentially result in a vibrations in loose places that resonate at it's harmonic frequency.

i'm not especially set on anything in particular, just trying to think long term,  dust, dirt, hair, etc and keeping the drivers clean

When I put the Vibrolabs (classic) wooden cups on my 80i's, I removed the cloth totally, and I keep the drivers face down when I'm not using them, it looks nice too. So far so good, I've had no problems at all with any foreign particles on the drivers.

yeah, i'm pretty careful with mine, no young kids that will get to them, but i live in a pretty dusty older home, and we have dogs

one of which sheds pretty good, just trying to head off a potential problem ! lol

I think it might be best to send them in to Grado to fix them.

Yeah, the dog hair can be a bit of a problem, now I understand!

I've been listening to my 325's from my MBP, with the Schiit Magni/Modi for about four hours at a time for the past few nights, and I can finally hear all the detail that I've been missing with them plugged into the headphone out on my Adcom GFP-710. I can hear all of the micro details like I hear from my 80's no matter what the 80's where plugged into. The Schiit gave the 325's a nice tighter bass (much less bloated bass than with the Adcom), the mids also sound a bit more forward and more fun, and the high frequencies sound just right to me, and the clarity is much better out of the Schiit. All in all I'm happy with the way they sound, and for 200$U.S., you can't go wrong, nice little system for the MBP. The 325's are much more picky with what you feed them, and its not like I fed them crap, the out Adcom is just amazing with the 80's, but the 325's just didn't like it. I'm still waiting for the tubes to burn in more on the LD before I give the impressions with the 325's.

Sorry wrong thread.

post #3563 of 4875

Certainly not an expert, but when I was setting the wings on this pair, I did a lot if tap and listen, to ensure equal sound response on left and right. The effect was perceptable during the sanding and finishing steps, and very noticable while placing the screens. I finally settled on a thin layer of contact cement where the metal screen touches the wood. Couples and dampens at the same time, shutting up the metal right now, and letting you hear the wood.

 

Encountered the same issue when setting the internals, but there wasn't really as much I could do about it. Assemetric weight between left and right side due to owner mod placing 1/8th stereo jack on one side. Secured the wires better (and selected something in and audio grade), and epoxied the jack to the case to keep it from vibrating about. Still couldn't get them to tap out identically. I suppose I could have glued a dummy jack into the opposite ear, but I was already way outside the scope and timeline for the project. They did sound nice (to me).

 

 

Cheers!

It's not a big amount of modding, doesn't come close to what you guys do certainly. I have just mounted bare polished aluminum gimbals and rodblocks from Martin Custom Audio. My RS2i look rather stunning now:

That does look nice.

Looks nice! I love Martins hardware!

Hi guys, I traded a guy a set of cups for some Grado drivers and he sent me these.

 

 

He did say bare driver but I'm not a happy camper.

 

What do you think?  Should he have told me the how bare they are?

post #3568 of 4875
No...oooh...no grills...that's pretty crazily liberated...are the functional? What model are they from?

that ain't right... I'd be pissed!

post #3570 of 4875

They are Sr60's and I haven't tested them because I don't want them in the condition they are in. I have to say that the guy is new to Grado modding so in liberating the driver he probably didn't know exactly when the liberation was over. confused_face.gif
