Also, it was mentioned earlier that the Koss KSC75 drivers might be sufficient for testing.  The driver is the correct dimension in order to fit the cups, but from what I've read, the driver doesn't do as well in open Grado cups.  The driver itself does work in open-air / vented mode in the clip on Koss headphones, but with the Grado cups, it appears to be a different story.

 

just my 2 cents but I think an SR60 donor would be ideal. go for it! :D those drivers deserve better than plastic

I used some KSC75 drivers in my Paduak cups for a while, as well as a pair of Sportapro drivers. I was going to do a StatoKOSSter, but never got around to it. They are nice in a pair of wooden cups, but from what I could tell (with my wooden ears, mind you, YMMV) the cups were little more than an aesthetic upgrade. I am assuming the real improvements on the drivers come when you seal off and damp the cups. This effectively almost completely rules out wood as a factor on them.

 

Again, you might find I am completely wrong though :D

 

I feel your pain Wje. I am also on the cusp of liberating my SR80 pinks but just can't bring myself to desecrate them. They sound so damn good stock. They aren't a pair of Magnums, and they even get beaten out on clarity and detail by a pair of SR225i, but yet...

I've been trying to get a coordinated time when I can purchase the pair of Grado SR-80 (non "i") headphones that I can purchase locally from a seller.   Unfortunately, those times are not really matching up too well.

 

Meanwhile, I've opened up my options and areas where I'm looking for a pair of headphones for this cause.

 

Thus, I've created a WTB thread here in the Headphone F/S forum.  So, if someone has a pair of SR-60 or SR-80 Grados that are collecting dust, check out my thread, and give me a shout.

Thank you.

6th period I'm in te computer lab and I don't have band after school, so that should HOPEFULLY give me the time I need to write the review... Good luck WJE!

So excited about this! I'd love to get involved (I used to own a pair of 225i with mahogany cups) but I don't trust myself in cracking open my Grados :p I look forward to the reviews though! Wood has an interesting effect on the lower-end Grado drivers.

I'm with you. I've been loving my Grados 80 since the 90's. I just ordered replacement earpads for them. I couldn't stand the thought of anything bad happening to them. :basshead:

If something did happen to them I don't know what I'd do. wje's post about having a hard time finding a pair has me worried!

I should, or will, be in a position during the coming week to take on the driver / tone wood testing to keep this going.

 

Sadly, the guy with the SR-80s did send me a PM on Tuesday eve as I was heading into a 2 hour meeting.  I responded via text, left a voice mail along with an e-mail response.  He has not responded to my inquiry, so I think that option is a dead end.  Hopefully, I didn't come across as a stalker by blanketing him with messages from all sources.  :ph34r:

My review has been posted on the first page, and the cups are on their way to WJE as of today. Feeling great :)

Great review, the birch didn't get much respect, no wonder they don't use it to make guitars.

It will be interesting how the next reviewers rate these tone-woods.

post #25 of 211

Good review! Interesting to see that the Walnut came out on top. I'd love to see how Mahogany compares.  

post #26 of 211

Good stuff! Very interesting to read. You should ditch some of the poor sounding woods and add some more dark hardwoods or exotics in the mix. I feel like Mahogany would be a good bet and easy pick up as its relatively similar to walnut.

later this year or early next year 7Keys is going to make another couple cups with more exotic woods, and include the winner of this round. smily_headphones1.gif

also, remember, if you want to participate in this just shoot me a PM and we can get started.

This is a very interesting experiment.  If I felt comfortable "liberating" my drivers, I might join in.  But I'll spectate for now.  when thinking about the different signatures of the woods, I guess it makes sense that the harder woods are reflecting more high end, and the softer woods are absorbing some.  you should add some more hardwoods.  oak would be a great candidate.  I wouldn't have thought it to be so obvious as you seem to have found.  I continue to watch with interest.

How exactly are you able to test them?

 

Do you have all 4 variations of the same headphone with different wooden cups and possibly a stock for comparison? Or are you effectively building the headphone each time and going off sonic memory?

This is essentially just an "experiment" or a test of impressions on the various (4 types) of wood.  One is not building the headphone each, time.  The cups were just a basic "cup" that has holes for the gimbal mounts, as well as a rim to hold the ear pad on.  The cable hole has a slit in it where one can easily take the drivers from one type of wood, then move it to the next wood and install the pads, then continue testing.

 

This thread will not result in an end all, be all final decision on what the best wood type for cups will be.  We're just testing 4 variants to discern if there is a noticeable difference between the woods when it comes to sound - whether improved or affected in some way.  For myself, I have music that I've heard many times over the past decades (yes, I'm 50!) and know many passages in the music - as well as various vocals by the artists.  It is those passages that I'll listen to carefully to see if there is a noted difference.  It might be a jazz track with great percussion or an upright bass.  It could be blues and I'll tune into the bass guitar sections and drums, if they're present in the song.  Finally, female vocals - depth, etc. will be carefully scrutinized to see if they could change or be affected by the various wood types.

 

The 4 cups arrived at my home today and I'll get into the testing most likely at some point tomorrow.  I'm looking forward to this event as I did a face-off between two of my Grado models and it was pretty interesting to note the variables.  I still need to post those results - but have to refer back to my 2 pages of notes, as well as a grid where I would score the headphones based on various aspects of the music and how the headphones handled it.
