If the guy has typical audiophile box speakers, it will be like comparing a SET amp and CH Precision - polar opposites. Now if the guys says, say a horn driven by Kondo Ongaku, this comparison will be much more interesting
Your analogy is incorrect. As for what the guy has, he introduced me to my first horn speakers ever. They were his DIYed, many years ago, and I wondered how a horn and a midrange as transparent and as agaile as my electrostats. I later would make the connection that horn beryllium drivers like TAD and Radian have that electrostat similarity. His were TADs. I heard them with very low watt SETs, and loved the Lampi.
As he is a dealer/distributor he also has now horn, panels, and cones, and things like audionec. So the compare can be done on any or more than one.
