Steve used to make passive preamps so most of his amps should be compatible.
Is that like ‘ModSquad’?
The manual says:
Input Impedance: 100 kohm
Input Sensitivity: 0.870 Vrms
Voltage Gain: 30.5 dB
Frequency Response: 3dB ~ 5Hz, 200 kHz Signal to Noise: 100 dB, "A" weighted
Signal Polarity ("absolute phase"): noninverting
It should be fine with anything except a phono preamp.
The OP’s other tread said something about a tube phono (I think).
Ergo… I would call:

Might as well post the answer here.
As an aside if the output impedance of the tube phono is 100-ohm, and the input impedance of the McCormack is 100k, then what is the out impedance as seen at the tail end of the Belairi?
With the Barali running at -30dB, is it 33k or 1M, or something else?
The idea of interconnects not mattering at is pretty correct when the output impedance is close to 0 ohms. At tens of kilo-ohms, then any inductance or capacitance might have more of an effect, and could make interconnects matter more.
FWIW… I would avoid the red boxed dimmer switch.
