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

@auxinput: Well, I think the best way that the Crown D-75 can sound is in stereo, because each amplifier has its connection balanced or unbalanced and is not divided for 2 amps, as it is on page 6-1 of the service manual; in My opinion, the best way they can sound is to put them both in stereo and connect the right speaker on channel 2 of one of them and the left speaker on channel 1 on the other, both in stereo, so each internal amp has its conection. what did you think? thanks :-)

yeah, that sounds like a good plan.  If you have two D-75 amps, use one for left speaker and use the other amp for right speaker.  That way, you are not sharing a single amp power supply for both speakers.

@auxinput: yes, but not in mono, in dual channel but using one of the amps for a speaker :-)

Right.  If you have two D-75 amps, it is better to use one amp per speaker.  But not in bridged mode.  The power supply from one amp is only used to power one speaker.  This is better because a single amp power supply does not have to push two speakers.  You will get better results.
