Default THAT1646 DIFFERENTIAL OPAMP

Has anyone come across the THAT1646 fully balanced (in and out) opamp?

Balanced, transformer-like floating
output
OutSmarts
technology improves
clipping into single-ended loads
Stable driving long cables and
capacitive loads
High output: 18Vrms into 600
Low noise: -101 dBu
Low distortion: 0.0007% @ 1kHz

Industry-standard pinout

Audio Mixing Consoles
Distribution Amplifiers
Hi-Fi Equipment
Audio Equalizers
Dynamic Range Processors
Digital Effects Processors
Telecommunications

I thought it may be useful to allow very low dac i/v resistors (~15R) when using 2 dacs in differential configuration whilst providing balanced output to drive a transformer, valve or opamp output stage. However only provides 6db gain.
