One of the tweakier things I've done. My twin brother is back in the states for a month and brought a couple of pairs of KZ ZS-6s with him that he has had for awhile. He had previously talked me into buying a pair of KZ ZS-10s, but I found them unlistenable due to their excessive high end. A few months ago, I had run across a post on diyhifi from Thorsten Loech (aka, Kuei Yang Wang) regarding some mods he had done to these. These are apparently a clone (looks-wise) of Campfire Audio Andromedas, which he apparently liked. Patrick (EUVL) on diyaudio also did this and seemed to like them, so WTF. Like I need something else to do right now. I sent a link to this to my brother, and hence, here I am trying to solder shit much smaller than I am comfortable with

So after some fun, I got both pairs of them done, and surprise, they are actually quite listenable for me! I really kind of like them, but still need to tame the high end a bit. At least my brother told me if I did this, I could have one pair of them. Listening to some Catherine Wheel Chrome right now (still one of my favs... those guys were fucking good!).

Stock, they are like this:

After removing a miniscule cap and resistor (102? barely the size of the end of my tweezers), and rewiring the balanced armature (BA) tweeters from parallel to serial, and replacing the resistor with a 7.5ohm MELF and the cap with a reasonably sized Panasonic ECP-U, they look like this:

Sorry for the fuzzy iPhoneXR pics, but best I could do this time of night...

Quite little for my taste...

Did you use a magnifying glass?

Glad it went alright.

I find it amazing.

Pars, do you wear any kind of glasses (or magnifying glasses) for these jobs?

It starts to have eyestrain problems and it is hard for me to see very small things. 

I use a pair of Optivisors with the strongest (10x ?) lenses. If I did much of this stuff I'd be getting a microscope...

 

not for my sausage fingers thats for sure!
