The Freya uses discrete J-fets as it's output stage, the opamps you see are most probably for dc servo duties because it's dc coupled, which even the $$$$$$K discrete preamps have.
From Schiit:
"JFET Buffer
Gain: 1
Frequency Response: 20Hz-20Khz, -0.2db, 3Hz-500KHz, -3dB
THD: <0.001%, 20Hz-20KHz, at 2V RMS
IMD: <0.0015%, CCIR
SNR: >110db, A-weighted, referenced to 1V RMS
Output Impedance: 75 ohms SE, 600 ohms balanced
Topology: Single pair JFET per phase with passive distortion cancellation, DC coupled"
