I was going to buy the G4, but the day the 5th generation was announced and I took the risk.
I've already used Yamaha and Genelec in the studio where I work and I wanted to have a versatile monitor, that could have enough bass and details for me to be able to mix at home.
In conjunction with the DT 900 Pro X, I have remade some mixes and the results have been great!
However, changing the faceplate is very difficult and besides it has 3 modes, it's a pain to have to lift every time I want to use the mix or focus (I ended up leaving just the mix mode)
It could have bluetooth to facilitate this process.
