1974 Engineering Policy (pt. 1)
1974 Engineering Policy, part 2

KENSONIC was formed by an engineer from Kenwood, Jiro Kasuga, in late 1972. According to Zeljko, Kasuga wooed on the way some engineers from other prominent brands (Marantz, Luxman) and the original departure of Kasuga was due to conflicting views about the follower of Kenwood's SUPREME 1 unit (1967, here).

However, Kenwood had shares in the newly formed brand... As a matter of fact, if one looks closely at the parts used by Kenwood and Kensonic throughout the latter's early years, one will quickly notice many a common one: may those be knobs, buttons, tuner dials or the general direction of the design with its slanted silver sides. Accuphase's early PCB's are tagged KENSONIC, too, and the early units bore a proud KENSONIC on their frontplates as well. According to mid 1990s reviews, Kenwood still owned part of Kensonic and it seems the Accuphase engineers may have had a hand in the engineering of Kenwood's last high-end series (L-A1, LD-1 and LV-Z1). Kenwood having since then withdrawn from almost everything, perhaps Accuphase is now fully independent.

The 1st units to come out of Kensonic were the
P-300 amp, C-200 preamp and T-100 tuner, quickly supplemented by the E-202 integrated amp and a revised version of the tuner (T-101). All of these received much much praise throughout 1973 and 1974 and, while Kenwood has now abandoned all High End audio activities, Kensonic still carries on with its ACCUPHASE series.
Besides phenomenal transparency and obvious long-term quality, Accuphase units always remain available for several years, sometimes up to a decade. They still do, and more, in the lucky owners' homes.

Unlike most manufacturers, Accuphase has kept its entire production available online - PDFs at any rate: here.
