Does anyone have any experience using these active monitors from Mission for home use? It claims to have been designed to accommodate home hi-fi use and features a line-level, single-ended (RCA) input. Does anyone know what the input impedance on this line-level input is? I would like to know if it's possible to drive these using tube preamps with 1k ohm to 2k ohm output impedance. Thanks.

I don't have any experience specifically of the Mission 'speakers, but
25+ years of active 'speakers generally.

I would expect the input impedance of the 'speakers to be 10kohms, so
it would be perfectly possible to use them with a pre-amp with a 1-2k
output impedance, using typical domestic-length coaxial cables to each
'speaker.

The problem with excessive cable lengths is that the capacitance of the
cable will cause the treble to droop. However, with cables having a
typical capacitance of, say, 150pF/m and a cable length of 10 metres,
the 3dB point will be 50kHz with a 2kohm output impedance, so unlikely
to be a problem.
