NXP   BF862, available from  digi-key.

I have used it in a similar hookup with good success. Its  virtue is the
low noise voltage AND low input capacitance at the same  time.
You could deploy MANY of them in parallel until you get
into the  capacitance range of a single Interfet device.

One heroic effort for  audio is here:

I currently use 3 pairs of SSM2210 in front of a  AD797.
