Thanks for your reply, I was pretty sure that "passive" was not what Steve ment. The term that I have seen used for the concept Steve was referring to is "buffer" amplification and is also used for impedance control of the pre-amp output stage.

BTW, most antennas have some directivity. Even dipole antennas, prefer horizontal incidence,

These are "straw man," arguments. I think you should just admit that active preamps add gain and stop trying to refute points I did not make. I will not even entertain this one.

Never become so involved with something that it blinds you.

I am the only one that noticed Larry Greenhill's equipment list includes Theta Prometheus amps in the last Stereophile? I am guessing this means that he is the one that is reviewing the Theta amps.
