Update.
Have moved the speakers into my listening room. Boy these demand a lot of real estate in the room which is 14.5 x 9 x 21.3 feet.
Unfortunately I cannot move my main speakers out of my room so I have the Harts directly in from of my main speakers.
Have them separated as much as I can and the results are ok but too close really to my listening chair.
My room is also a "movie room" which is shared with my music so I have a rear elevated platform with a sofa, the viewing gallery.
Anyhow have tried two amplifiers (Classe DR3, Wyetech Topaz ) with them and two make a hum that is just too loud for listening.
These two amps are dead quiet with my main speakers so what gives ?????
Used cheater plugs, moved power cords, moved speaker cables etc to see if this would help but same result.
Being frustrated I brought in a little Naim Nait 5i which is used in the family area and no hum at all......
So my go to amps are too noisy for the 16 ohm Harts but are fabulous on my main speakers.
Does this mean the Harts are like an electric microscope which brings forth any amplifiers misgivings ?
I know that vintage amps of the Hartsfield era may have had 16 ohm taps available on the amps.
Should I be looking for vintage amps/gear ??
Thanks for reading.
