Not quite, the Tyson family from Peter Tyson retailers have developed this brand. The two Tyson brothers developed and designed the amp over a 3 year period. So it's their own in-house brand as opposed to just being an exclusive distributor.
Playing Devil's Advocate here, but what do we know as solid facts? Promotional videos can say what they like, but there's a possibility these have been designed by an OEM company, or made by a company who produces their own audio equipment. These could have been produced under license to a third party company. We just down know. Audio engineers design hi-fi, what would a retailer know? Basics maybe, maybe a little more, who knows, maybe they're trained electrical engineers who know audio products inside out? But as owners of a large online sales website, I would be dubious. Maybe they had a say in how they wanted it to look, what they wanted it to do, which would fall under "design", maybe even "development"l I have a design for a pair of (what I feel could be) awesome speakers, but that doesn't mean they're going to sound any good - I'd need audio engineers to tell me that.
And technically, they
are exclusive distributors, whether they keep it for themselves or not. And if they don't make the brand available to other retailers, they're also exclusive retailers. I don't really see this as any different to a retailer who takes on distribution of a hi-fi brand (something I'm against).
