The owner of Symphonia was Vincent Testa, a fellow Melburnian I have met. He is a sales/marketing guy; he was in partnership with a another chap whose name escapes me. They had developed a system system which eliminated the switching spikes of Class AB, and from all reports it was successful. However, I last met Vince about three years back; he had closed his shop, and was developing the amp business.
He is a highly colorful character, and it may be that he's out of business. He was pretty cheesed off with the industry as I recall, it's possible he's now out of business. Not much help, but a glimpse of the business.
Cheers,
Hugh
