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

Balanced, transformer-like floating
• 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.
