It’s the other way around. You want a SS amp with higher input impedance to work with a tube-preamp. 100kohm is a good input impedance to look for but as low as 40-60 kohm may be fine. My combo is Audio Research sp16 pre to bel canto ref 1000m monoblocks. See system pics.
Tube Preamps that work well with SS amps?
I'm looking for a tube preamp after years of strictly SS. My amps will remain SS. Which tube preamp(s) in your experience mated well with a SS amp? I'm trying to avoid the odd phenomenon where tube preamp + SS amp = slow, soggy sound in spite of benign impedance characteristics
