Grado modders go Magnum - Page 212

post #3166 of 3174

ok, so I just bought some SR60i's on sale, and am doing a trade for some 80i's, so I'll have a couple pairs of Grados in my hands very soon. I also just discovered the Turbulent Labs site, and have been browsing the few Grado modding options on their site. That lead me to this thread, and I have looked around a bit, but with that came some confusion.

 

Can anyone help explain what Magnums are exactly ? I get that they're drivers (right?) but if I try doing a Google search, I just get the Turbulent site - and I don't see any Magnum's on there. Same w/ Symphones… What is that? It seems it was a canadian site, but it isn't online anymore…  I keep seeing references to stuff but I can't seem to figure out what it is. I'd love to read through this entire thread, but it's a little long… actually, it's VERY long. So basically, an updated / modern introduction or primer on modding Grado's is what I'm looking for, if anyone could be so kind. 

 

Thanks!

A pair of Magnums used to be a complete build done by the Canadian site you reference. They were a stock pair of SR325is, with the original Grado drivers and plastic inner sleeves removed and replaced with aluminium inner sleeves and specially made drivers...Magnum drivers. There were five versions of the Magnum driver (with a few versions between whole numbers in between apparently). The fifth is the driver you see being sold on the Turbulent site. The aluminium gimbals and sleeves are no longer available. Neither is the build service previously offered by the Canadian site.

 

Note the "M" logo on the sleeve.

 

 

Note the aluminium gimbals replacing the stock plastic Grado ones as well.

 

The information found here is old, but pretty much covers the basic Grado mods:

The real fun with Grado modding comes when you get to replacing the stock plastic cups. Depending on creativity and resources, you can make yourself a pair of headphones for life. People make endless variations on the theme: wooden outer cups with aluminium inner sleeves, wooden inner sleeves with aluminium outer cups, one-piece full-woody cups (a-la RS1 style), outer cups made with one type of wood and paired with inner sleeves made of another...and the possible shapes are endless (do a Google image search, its fascinating)...

 

People generally use their Grado drivers, or upgrade to Magnum drivers (the Magnum are generally better than stock Grado drivers, but sometimes implementation and materials changes that). They also upgrade the stock plastic headband cushion with a nice leather one (the Turbulent headbands are the best aftermarket ones I have seen, but I never managed to get my hands on one of the much-lauded, now unavailable JMoney ones).

 

They also change the pads around, trying the G-Cush, L-Cush and the TTVJ flats to tweak sound as well...

interesting… thanks for that. So, you can't get aluminum sleeve's / gimbals anymore? That's a bummer… Are there any replacement sleeves available anywhere (apart from second-hand)? I will probably upgrade the headband, and get some wooden cups, and probably the Turbulent driver as well as long as it is an improvement over the stock 60i or 80i driver. And between the 60 or 80, is one more suited to or commonly used for modding?

 

Thanks again -

No problem...indeed, the sleeves and gimbals are no longer available new. I know Martin Custom Audio does aluminium gimbals, and there have been a few one-offs done by avid modders with access to the right tools and materials...no sleeves though. I have looked at local machine shops myself to get them made, but it isn't cheap, and usually they aren't too excited about doing a fiddly little one-off job for someone.

 

The Turbulent driver is indeed an improvement over the stock SR60i and SR80i driver. Personally I use an old pair of SR60 drivers to test cups that pass through my hands. Both the SR60i and SR80i are equally good for modding.

 

I keep some vintage pink SR80 (another story altogether) and some Turbulent drivers for my everyday headphones...
