You may contact Greg Collins at Sedonix@commspeed.net or at 928-284-0884. Greg is not the AA distributor but just a repair site and I doubt he enjoys receivng all the calls asking for information. I am finding that Greg can fix the units properly. My understanding from another Greg at United Home Audio (866-482-8346) in Washington DC is that Audio Aero will be looking for another US Distributor soon and the letter he read to me (from AA) stated that Audio Aero was alive and well but wanted to make the best decision possible on a distributor. At any rate the French have a different interpretation of service than we are accustomed to.
