Shelby,

Well Shelby what can I say? Never in my wildest dreams did I imagine to have a normal conversation in a Cessna 310.  It's just amazing what you're A.N.R. system does. The 
noise level in the cockpit was so low it convinced me to put this system in my Aerostar 
601P.  Once again Shelby it is just amazing.

Best regards,
