I have a Suhr Reactive load (guitar amp speaker load simulator with line output) that has a 10k balanced out for feeding a line level guitar signal to ADC input for speaker cabinet impulse response software. With the unit’s potentiometer turned down to 5, the impedance is about 2.3k. Many users have reported the 10k unbalanced out sounds better into an instrument input and the newer version has been changed to a buffered 600 ohm out.
I would like use the balanced out to present a clean, balanced low impedance line signal to my ADC via a voltage follower.
Is the attached fully differential line amplifier appropriate for this task? It is described as “positive feedback / active termination”.
It is described here on p.10

Is there a type that would be better suited?
Can I get away with a single supply voltage to use a wallwart instead of building another supply?
THANK YOU!
