Thankssmile.gif I applied 4 layers of wood conditioner to the inside and outside (dewaxed shellac) and then rubbed in about 7 coats of Birchwood Casey Tru Oil (a gunstock oil). Working with clear vertical grain cedar like this is much like working with a dense urethane foam. It has an excellent stiffness to mass ratio and is very easy to work with but the surface can be fragile. Applying the wood conditioner and oil went a long way towards creating a shell like surface but I will still have to exercise caution to keep them in good condition. 

 

 

Aha. I am quite familiar with Birchwood Casey's products. Never thought of using them in this application though. Good thinking.

I re-used the original strain relief (rubber and metal bits) and the cable is something I found in a drawer and is of unknown origin. It is roughly the same length as a stock HD-650 cable and has a 3.5mm stereo plug at one end (with a screw thread for an adapter) and it used to terminate in two 3.5mm mono plugs at the other ends, which I cut off. It also has a nice plastic block just under chin level to prevent the wires from separating further... It's made of pretty substantial copper and looks like it was made for the job!

 

Sounds like an old Senn HD2xx cable.

Gonna ask again, anyone here have a Sansui SS-100 they'd be willing to part with?

Nothin' new 'bout this headphone, but I tought I'd show you a vivisection of the Leak3000 anyway. Bought from Mr Steptoe in UK, might have passed the hands of Kabeer (?) or someone else who opened it and removed the cardboard between felt and driver. Modification will commence this weekend.

Third from the top is kinda how you'd expect a headphone labeled Leak to look.

Ortho transplant challenge!

 

I'd like to see someone have a go at these......atsmile.gif

just finished re-recabling the SFI ES7, now it is more correct-sounding than the one i did before, it seems that i need to remove the silver coating from SPC cables first before i start soldering them to the drivers and jack.

 

no damping, it basically sounds like an ath-2, which is what i expect. and for some reason, most materials that i tried leads to one thing, bass become very thin and too much upper treble? not sure, its the part where the hi-hat goes in some rock or pop songs. i even tried to use those accoustic foam without cotton material and it only shows the same result. i thought that the accoustic foam are obstructing the vents i made on the driver-side baffle and cups, so i tried cutting the foam to let air move to those holes, and it sounds the same, sadly.

 

i ended up using a layer of the arctic cotton that is not teased and bass is still boomy but not as worse on my description above which is very bass-light, and added another layer and it sounds about correct now, no more boominess, vocals are clear. the problem now is that the hi-hat from some rock or pop songs i still too loud, although it is tolerable, the sound is crisp and clear, similar to the HE5-LE that i have owned but without the "too loud" part. i want to make it tone down abit more, i also want to make the bass give abit more body and impact, bass boost from my E12 is not working at all in that headphone, haha! maybe i will change one layer of arctic cotton to another material to achieve it.

 

ill post pics after i finish damping it. might as well make the mirror-like cups have a brushed finish, but still thinking of a better way to make them "brushed" equally. dont want to make another mistake doing brushed finishes by scratching the back with a sandpaper like a hungry, ravaging bear at the back of my ipod touch.

Sorry, can't help out there because my spare drivers are ready to roll with sauve class in these shells. I like to keep my music HOT.

Great, MDR30! I recently bought a set of these too (mine are Wharfedale, but the same.)

"Cardboard between Felt and driver"? Do I dare investigate?

Does removing it improve things? 

I usually trust the designers. certainly the guys who designed the originals (ID1s) got it right I think.

Even IF the white case is a bit 70s!!

After years of using the original Isos (Wharfedale) I thought I'd try the round versions!

Will look with interest at your amendments!

 

I like the sounds from the ID2s. Haven't done a side-by-side comparison yet with the ID1s. 

Not directly comparable as 1s are OVER ear, 2s are ON ear.

But the 2s are much more efficient than he 1s. Can even use moderately via iPod.

Certainly via Matrix amp.

The 1s I have to take from speaker outlets on Hafler DH100, using Matrix as Pre-amp.

Well, I may have bee a bit hasty with that cardboard assumption. As a matter of fact there were only traces of paper with adhesive on the drivers, so that may have been it as far as I'm concerned.

 

 

The sound of the Leak3000 was a bit closed-in when I got them, so I'm aiming for some clarity, punch and air. We'll see if any of that is attainable.

Oh, just a man selling a pair of old headphones on a web hifi market. He said "they have large membranes and sound good".

The model number ASE50 excited my little grey cells, after having spent too much time on wikiphonia.

Good Catch!

 

Not exactly great ad copy there, so we will await your initial review eagerly.
