Also interested in this - having the bird with the 1960, I’m keen on a pair for my other IEMs.Thanks. What's the main differences between the 1950s and 1960s? I believe the 1950s is better paired with bassier/warmer IEMs like LX, and 1960s with airier/brighter IEMs like Fourte. Not sure why or how, just what I've read. If that's true, I have a use case for both.
These PWs seem like a bit of an enigma - think it all comes down to synergy. I know the 1950 is often paired with bassier IEMs but the 1960 can work great too....if I recall correctly, @twister6 really enjoyed the pairing of 1960 4W with the Noir.
