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

AD1955 has differential current output (two current output pins).  In order to make differential voltage output (balanced output) it needs two current to voltage converters.  OPA2134, being very low bias current dual amp, is good candidate for that.
joser9616,  you're welcome.  OPA2134 has also high current drive ability making it a good choice for an output amp (combined function of I/V converter and output driver).
