You're absolutely right mvs0, it does have very low distortion in simulation as well. Apart from the insertion loss, the other potential issue is the low impedance of around 850 ohms, but if the source can handle it and the insertion loss isn't a problem, it's a pretty neat solution.
Note that the second stage is only there to get to right clipping level for my application.
If your amplifier has some form of volume control you can get rid of this stage.
Without it the insertion loss would be less than 3dB.

That is highly unusual. Multiple members have requested more information in order to be able to help you. After a few weeks the only information you provide is "it not a bridge 185V/85A". Asking and receiving help is a 2-way process.
