Klaus has stated 10Kohm's, MGalusha measured 18KOhms on his mono's I beleive.

depends on your volume control. Default Foreplay is fine, regular sweet Whisper's will be too loud, and even the -20 to -50 may not be very useful.

I have a custom attenuator on my Foreplay that's about -27 to -68 db, which at least with the Extreme Monos is a very good match.

input Z of Stratos is a function of date of manufacture: my "green board" Stratos Plus was approx 18K, "red board" Mono Extremes are near 11K. no obvious electronic reason for the change.
