Hey thanks I actually got a hold of him a day ago and he was very nice and helpful. He told me he has an update for the hissing sound and told me when he is moved and the units have been tested he will update my speakers.Andy just moved his shop out of state. I am not sure if he has updated his website yet. I will try and get a hold of him for you......
