After completing a PhD in electrical engineering at Imperial College London, Floyd E. Toole joined Canada's National Research Council (NRC), where he would stay for more than 26 years doing audio-related research. He continued his research at Harman International after leaving the NRC in 1991. When Toole left Harman in 2007 (footnote 1), Harman kept the work up under NRC alum Sean Olive—which fact surely has much to do with the excellence of their current loudspeaker lineup.

The two biggest sonic jolts I've experienced involving phono preamps were from two very different ones: the Petr Mares's Connoisseur 2.0 and Boulder's 2008, which was reviewed in the July 2002 Stereophile. The first was hand-built, single-ended, housed in a wooden case, limited to 100 units, and, when I got to hear it in the mid-1990s, cost around $6000, or about $10,000 in today's dollars. The other was a feature-laden, double-chassis monument to flexibility and surface-mount high technology. It featured beautifully finished, flush-mounted mirrored buttons your fingers just wanted to press.
