Dropping in a balanced out solution on my DG-1000

Hello again.

I am designing a breakout board to replace IC205 on my DG-1000 preamp, in order to add a balanced output jack. I am planning on using it add a THAT 1646 balanced line driver in addition to an OP275 (replacing the NE553) driving it. I just wanted people's thoughts on the implementation - I plan on following the suggested circuit schematics on the datasheet for the 1646/1606.

Is this a good implementation of a balanced output for audio equipment?

Thanks in advance for any input.
