Hello,
it needs an opamp with at least +/- 22V power supply, DIP socket. I found the OPA551.
I wonder if it is suitable for audio? Like a preamp stage?

Yes I think so.
It is a very powerful opamp. 200mA. And +/-30V
Alternative is OPA604

Yes, used this opamp many times in headphone amps and preamps. It works very well.
