It is balanced or not?

Hello everyone, I am new to this page, I thank the Audiogon team for allowing me to be here with you, I have a question: I have the preamp and DAC: "Emotiva Differential Reference XDA-1" it has the following digital inputs: "S/PDIF (optical and coaxial) and AES/EBU (XLR)", the XDA-1 has balanced outputs for an speakers amplifier, inside it has the amplifier: "Texas Instruments Burr Brown OPA2134" and I want to know if it really works balanced; the XDA-1 has the DAC: "Analog Devices AD1955" inside. thanks

The op amp is a factor in sound quality, but it's never the full story.  You also need to look at power supply, etc.   The fact that the JBL uses a switching wal-wart power supply is an indicator of poor sound quality.  The JBL is meant as a cheap mixer / room correction unit.  I believe the Emotiva would have highly superior sound quality, especially since it has a fully discrete output stage.

Ok, thank you very much, but if I connect the Emotiva to the JBL MSC1?, The Emotiva is digital and it has unbalance and balance output, I want to connect that output to the JBL MSC1, what do you think?

@auxinput I do not understand why it can not be balanced by having a mono and bridge option, it is very rare, that amplifier has been used for many years in professional studios and has even been described as almost high-end. Did you see any diagram of that amplifier to know those details?
