Streamer/dac direct into Music Reference RM-200?

@clio probably knows and the answer is likely yes, for hints look at output impedance and voltage for any of Roger excellent preamps… RIP legend and genius

Search yielded this… might be accurate might be applicable to mk 1 also

• Input Impedance: 15k ohms (single-ended, one leg driven), 30k ohms (balanced)
• Input Sensitivity: 1.1V for full output

Thanks @tomic601 for the input.  Do you still have RM9?  I'm anxious to get another MR amp back in my system.  Had a RM-10MkII years ago and stupidly sold it.  Roger was a treasure - spoke with him on the phone a couple times, RIP.
