Audio reserch reference 3....driving Nagra VPA amp


Just a quick and simple question....maybe someone out there know if audio researchs new reference 3 pre-amp matches well with Nagra VPA 845 monoblocks....i am tempted to make the dive but have no way of trying the setup before buying used pair of Nagras, any input and feedback would be greatly appreciated.
Best regards

The Nagra has input impedence an sensivity below:

Input sensitivity: 400mV for maximum power. Input impedance: 100k ohms

the reference 3' output below:
OUTPUT IMPEDANCE: 600 ohms Balanced, 300 ohms SE main (2), 20K ohms minimum load and 2000pF maximum capacitance

The Nagra has only Balanced in's and thats the way i want to drive them trough the reference 3, so basicaly 600 Ohms in balanced mode for the output.
I want to drive a pair of TAD horn speakers, 2 15" woofers with a compression loaded 2" horn.
Their Nominal impedence is 4 Ohm's and the sensivity rated at 98Db.
