That makes a lot of sense Klaus, so I guess I should sell this and get a proper cable, I’ve been looking everywhere and haven’t had much luck.
Hello Klaus, i received my neumann z48 shock mount.
It is so nice but i realized that the diameter of the top ring is larger compared to the bottom ring, i suppose because it contours to the u67 mic body, but the top clasp doesn't hold tightly like the bottom clasp, is that normal ?
Makes me worry as i hang my u67 upside down because of the heat from the tube.

With the mic properly fitted, both clasps should have equal tension when closed.
Move the mic up or down inside the mount, to get even contact with the felted rings.

Thats what i did, out of curiosity i held the mic and closed just the bottom clasp and the mic slips out, i tried the same thing with the top clasp and that holds the mic tightly.
Definitely doesn't have equal tension.
Mine almost seems like the top felts just barely hold the mic, more of a guide while the bottom tension is strong.On another note if I position the microphone the proper way meaning the head basket is on top then there is no way for the mic to slip out even with the clasps open because the design of the microphone stops it fr
om falling through where the head basket meets the body :-)
Does the heat from a tube really hurt or damage the capsule over time ?
This is the only reason I hang it upside down.

The top felt looks worn. Compare to new.
No heat issues with U67 and K67 capsules. Position the mic as you please.

I compared my z48 to the pictures on the Neumann site and I can’t see a difference personally, but if I don’t have to concern myself with the tube affecting the capsule then I will position my mic right side up, thanks again Klaus problem solved :-)

Can’t sleep and I’ve been thinking about maybe not selling my swivel mount,
One reason is it’s always nice to have a back up cable and the other thought is that would if I put a small patch of carpet underneath the mic stand to absorb a little low end rumble ? I know carpet can’t compare to the elastic bands in the z48 shock mount but just a thought ?
I think I might do a quick test and compare the low end ruble you get from standing doing a vocal with each and see how much of a difference there is or isn’t :-)
does anyone know if using a z48 shock mount will absorb 3db of noise versus not using one ? there may be some numbers out there lol
Update--
I actually just read a person on this forum saying they did a test using small pieces of foam under the mic legs and that decoupled it better than a shock mount ?
gonna try this.
There is something about this u67 swivel mount that is so strong and secure and makes me feel at ease when recording.

..and considering how many seminal recordings have been made with this mic on a swivel mount: has anyone ever noticed the type of mount on any of these recordings, let alone complained about it?

I am certainly not complaining Klaus, just my observations :-)
After positioning the z48 I realized that I like to have the option of getting very close to the mic, which the z48 gets in the way, the swivel allows me to get right up on the mic if I need to so I am keeping my swivel mount and ditching the z48.

At least one of them is: the one with the outline of the spiral shielding poking through the silver jacket.

It will be the cable in the cropped section of your picture. I cannot give you further confirmation, as the connector sections are blurry.
As I wrote: only one of the cables has the distinct corkscrew shielding poking through. That's the one.
