@kota1 Also as far as wireless I assumed you and the man on the video were talking about transmitting the main signal vie RF or bluetooth to the speaker from the wireless transmitter that is a far different story than using a code like FM Play or a format like that using wifi for Roon of something like that is very different than sending the entire spectrum of music via a transmitter and receiver via RF.
@thespeakerdude Were these wireless connections RF or were they a coded signal like bluetooth or the like. I can't imagine such a cheep circuit in an RF transmitter with no compression. And of course the FCC is squeezing wireless microphones into oblivion with it's huge sale of RF spectrum to large companies and outlawing people with hundreds of thousands of dollars or wireless equipment that just happens to be in the wrong block. The FCC during the last administration was very cruel to people who owned equipment like churches and performing arts buildings that needed good RF.
