Most preamps ARE "OTL" - but they are not driving low impedance Amps - most amps have an input impedance of 47K Ohms - a tad higher than most speakers...
Happy Listening
Follow Ups:
Wouldn't it be more correct to say that most amplifiers have an input impedance ranging from 10K to 100K ohms, with solid-state amplifiers clustered at the bottom of that range and tube amplifiers up around 50K and above? "47K" is the standard load resistance for an MM phono stage, as I am sure you know.
