Input Impedance
Unbalanced: 20k ohms
Balanced: 40k ohms
SHOULD be OK, but Mc amps are designed with lower input impedances than some preamps are comfortable driving. For example, many amps have 100k ohm or higher input impedance, including all the ARC amps I looked at.
Not that it won't 'work' but they may not be designed for that. Seems like the SP-10 has a 250 ohm output impedance, which is low enough where it shouldn't be an issue, but hopefully someone with experience will comment.
Of course, I have to say that a used McIntosh C220 would be a great choice! which is what I use.
