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

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?
erik_squires the Emotiva Differential Reference DAC XDA-1 have two of the OPA2134PA
I read that from Burr Brown OPA2134 in its specs. but I did not understand very well, so I was in doubt that if that could mean if it was balanced, thank you very much for getting me out of doubt.
Than you very much to all!!!!! thank you than you :-) yes stringreen, the Crown D-75 and Crown D-75A are balanced, they are studio amplifiers(pro) oh ok gdnrbob.
Please people, which of these two amps have better audio quality? thanks:

it is inside a JBL Professional MSC1Studio Monitors Controller

it is inside of a Emotiva DAC Preamp XDA-1 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 :-) 
@auxinput: yes, but not in mono, in dual channel but using one of the amps for a speaker :-)
@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?
@auxinput Hi, I think I have something better than the Emotiva in my house and I did not know it, it's the Roland Mobile UA, it's a USB Audio Interface for headphones and it can also be used balanced to studio monitors: https://www.roland.com/global/products/mobile_ua/, it has this inside, amps:http://www.ti.com/product/TPA6120A2/description, DAC:https://www.akm.com/akm/en/product/datasheet1/?partno=AK4414EQ, and I think this works as pre amps: http://www.ti.com/lit/ds/sbos484a/sbos484a.pdf 
did you think this is better? thanks.
That's right, thank you very much for your help and the others here in this forum, the change was quite remarkable, much more sound quality.
The Texas Instruments OPA1642 works as Low Pass Filter FET-input opamps and it is used in high end receivers and the Texas Instruments TPA6120A2 works as Output buffers and they are high fidelity amps used in high end USB interfaces for headphones, it works balanced and you can conect it to an amp, believe me, more detailed sound.
@auxinput Hello, I'll be extremely honest, the Roland Mobile UA sounds a lot more detailed, with all types of music, Jazz, Rock, Classical Rock, Classical music, everything sounds better, it's a bit more on the treble side, but not in a way that offends or dislikes. congrats to all the fathers, have a good day.
