I have a pair of NVS Prodigy tower speakers I bought new from him in 2008 that I may need possible service on. I've been trying to find his contact info with no luck since he left the industry a few years back.
This is the last email I used to reach him, it was right when he was leaving the industry. contact@nvs1.net and a phone number of 408-569-6040. Good luck.. Duane is an awesome guy to deal with and has always been great about service.
