Thanks Steve for your help,

Do you more in detail?

The SL input (so the DSP8000.2) have a balanced DIGITAL input stage, but what happens AFTER the D/A conversion?
The D/A converter output itself are unbalanced, so the following analog power amps have to get in some kind a balanced input circuit.

So finally the questions for the whole ANALOG amp are:
- Is the INPUT/STAGE balanced-(made)?
- Is the OUTPUT/STAGE balanced ?

My interest is mainly the .2 version and the previous version that have SL inputs.

Thanks for any info
Robert
