Thank you

I will take your wise advice "If you’re worried about it don’t do it." remembering the sayings:
- If it aint broken dont fix it
- Curiosity killed the cat
Hi there I have a few other suggestions.
There are several options if you want to run your PS2000e balanced.
The first is like you say open them up and do the detachable cable mod.
There is a video of Custom Cans UK doing this on YouTube.
He had a tough time opening the cups and said he didn’t want to do it again.
So you could cut the cables just below the cups and solder on female connections.
You could cut the cables just above the Y split and have a 4 pin mini as a Y split and a new cable with 4.4mm at the amp end.
Both of these I’m sure Custom Cans UK could do if you didn’t want too yourself.
You could buy aftermarket cups from several companies and a cheap pair of Grados from eBay and make you own.
Beware this will become an affliction and you will grow to love mucking around making you own Grado type headphones.
You can buy different drivers , cups, rod blocks and headbands.
Cable wise there is a company on eBay called Skyaudio cable that make fantastic quality flexible cables at a very good price.
These are just some of the Grado type I made in the summer.
Both are super light weight and I can run them balanced or single ended.
The Rose wood cups use Alessandro drivers and the GS3000e cups use SR125 drivers from a broken pair from eBay at a cost of £14.50.
All the best and Merry Christmas.
