Default Good circuit for single end in to balance out?

As the title said, I'm lookng for a suitable preamp circuit that does a good job or taking single end in and output balance signal. I know some design works better than the other.

I have searched, but I'm not getting good hit.

Thanks!

Analog devices:

SSM2142

Burr Brown:

DRV134PA

Be aware, that these devices do require aditional ops to drive the line.

Use a modified Bride of Son of zen -- cascoded, with a single current source.

Somewhere in the database, it was opined that "Metalman's circuit" was the way to go. I used it and it works excellent.

The schematic was in one of the Bride of Zen or Bosoz or BZLS threads.

Or use a pumpkin, I don't have direct experience with the pumpkin, but I am sure it would work great.
