Sorry if this was unclear before. Your pairing with an Eros should be fine. It does have a rather high (though not insanely high) output, which might be an issue. You will need to try it to find out. Should you find it to be a problem, you have the option of using your lower ratio for a 4mV input, which is just about perfect.
FWIW IIRC, I believe the Eros circuit is more tolerant of overpowering the input. It will also sound better.
