I had the old cable (even 2) and now the new one, can't compare them as I damaged the previous ones but I would say the new cable is, firstly, of a better build quality and SQ is definitely better, fuller, better bass, warmer signature
Crabie can you say 4in1 is an upgrade to Pianos? I am thinking about 4in1 or kz zst now
If I could take bass and sub-bass from the Piano and mix with the mids and highs of the 4in1.....haha
I'm happy that I have both and if people start saying good things about the zst I'll probably end up getting that as well.
