I’m also considering the same between the sennheiser and AT. I have heard that the AT has a higher noise floor compared to a lectrosonic or Zaxcom. Obviously I’d prefer the lectrosonics or Zaxcom but due to budget I have to go with the AT or sennheiser. But how much in comparison to the sennheiser. The feature I like about the AT is the dual channel and the removable antenna. With that I can use an external antenna to improve performance which you can’t with the Sennheiser. But am I getting a much better system with the Sennheiser?
