Was looking at getting replacement wireless and was seriously considering quantum 5x offerings. Was interested in 6 systems. I liked their small transmitters. When I inquired for purchase in Toronto they referred me to Reynald Trudel at silent sound. I asked if there was another dealer and was told no that he was the exclusive dealer for their products in Toronto. Well sadly that was the end of my interest in their products. It's to bad they Reynald was the best that they could get for someone to represent the products in Toronto. Ended up getting Zaxcom and have not looked back. Hopefully they will find someone to better represent their products.
