Soulnote is a high-end home audio brand by CSR, Inc. headquartered in Kanagawa, Japan. CSR was founded in 2004 by the former members of Marantz Japan. It has around 50 employees now. Hideki Kato, the Chief Sound Manager since 2016, has his long professional career since late eighties, having deeply involved in the development of the legendary A-10 amplifiers by NEC as well as the LHH series by Philips, but having kept himself staying behind the scene. Soulnote's first launch into Europe was a couple of years ago with the models SA300 / SC300 / SD300 / SC710 / SA730. However, the current line-up is based on totally different design concept from that of the previous models.
