Wow! Sennheiser HD 540 Reference are so good. - Page 58

post #856 of 868

Okay, thanks for saving me some time and wasted paint. I just read your assessment of the K1000 from over 10 years ago. It's funny, back then, I would never have considered spending so much on audio.  I might see about getting a shabby or even broken K1000 when it arises so I can have a practice attempt on removing the red layer. Although if I were to screw it up, at worst, I'd have two spare K1000s and a spare set of drivers. After removing the red layer, does the metallic surface underneath have sharp edges?

Sod it, no turning back now. I've already started cutting and so far, I have no regrets. You're right; there is no way that any standard paint would adhere to that kind of PTFE material. The dull smooth metal underneath has quite smooth edges and gives off a mix of yellow, light green and red light. Careful wiping, sanding and consideration of this surface could bring out a shine. Painting onto this surface instead would give a much higher quality finish as well. I'm thinking a dark metallic blue. Now I've started this, I'm tempted to do the entire respray myself as well. I just want a beautiful professional finish on the whole thing.

Okay, don't want to dwell too much on the K1000 as this is a HD540 thread but here is mine after having the red layers removed.

I guess I'm not the only one crazy enough to do cosmetic surgery on a K1000...

By the way, my K1000 review thread from 2003 mentioned by CosmoMemory is still here, although the pictures are gone.

 

I'll refrain from further comments about the K1000 here, since this is indeed the HD540 thread.

I'm cringing at every step but I can't look away... :popcorn:

I think I need a 0.7mm hex key to release the headband metal pair from the assembly so I can remove the end of the red PTFE layer. It looks like it separates and I hope it does because this will make spray painting it easy.

 

 

UPDATE: K1000 bare metal headband pair now isolated from the rest of the earspeaker. Four 0.7mm hex key fixtures removed, allowing the metal to slide straight out of the slot and the red remnants easily slide off the end of the metal. All four of the black temple pads are also easy to remove. Carefully pull on each until the backing adhesive loses contact with the fixture plastic. This design is more modular that I had originally anticipated, which has its benefits for part isolation. Feeling really good about the disassembly so far. Nothing is damaged

Hello,

 

first post here, so please be gentle....

 

Have been enjoying my HD 540 Reference (600 ohm) from new a lot and was considering replacing it until I found this thread some time ago and decided it's a keeper.

 

But this morning the left driver died.

Opened it and measured on the pins that have the very thin wires attached: open circuit, so looks deceased.

 

Any thoughts?

I would like to repair but not spend silly money.

 

Thanks in advance,

Johan

Finally! A purpose for my single HD540I 600 Ohm driver! :bigsmile_face: A few weeks back, I managed to sever the contacts on one of my drivers when I took the cover off. There was some adhesive I didn't see, which ended its life. I'm pretty sure it's a 600 Ohm and condition is excellent. Hopefully it's a good match. I reckon it should be.

And it's alive again thanks to above posters driver.

Very happy to have found a 600 ohm driver which I get the impression are rarer than the 300 ohm ones.

 

Replacement is a 5 minute job once you've figured out how the thing clicks together.

 

Cheers and thanks,

Johan

Which modern day headphones are really close to a 540 and let's say no more than €400?

^ Dynamic headphones that is.
