Yup audiothesis, it’s all good! Newer enthusiasts are commonly scared off by warnings from more experienced ones, causing them to over-think things. That commonly involves the amplifier/loudspeaker pairing. But anyone contemplating ANY planar should understand they MUST have space behind them---the more the better, but hopefully at least five feet. Three is commonly quoted, but that ignores the 10ms "rule": the rear wave of a planar speaker needs to reach the listeners ears at least 10ms after the sound from the speaker’s front wave. Sound travels at approximately 1’/ms, so 5’ to the wall behind the speakers and 5’ back to the plane of the speakers creates the required 10ms delay. The ear/brain can then process the sounds as separate, rather than the rear wave as a smearing of the front wave.
moskaudio, do you have the 5’? If not, the ET, or any other planar, is probably not appropriate for your room.
