Hi Sarang and Dr. House,
Sandy Gross is not a designer/engineer. I have known him for many years. He was the former promoter par excellence and marketing guru behind Definitive Technology, whose speakers were designed by a French Canadian, Don Givogue, who has (or had) a Quebec residence not far from the National Research Council in Ottawa, where I used to run into him on occasion.
I expect Don designed the Tritons. He is a good speaker designer and while the DefTechs were quite good but with overly fat and heavy bass, I'd expect any speaker from Don would, at best, be "similarly good" to a pair of M80s. I don't know whether DefTech ever used the double-blind comparison protocol of the NRC.
Regards,
Alan
