None taken ... but if you consider the avg. quality of construction, components, and design of many Japanese brands they perform pale in comparison to the likes of Revox, Otari, Nakamichi, Tandberg, SAE, Soundcraftsman, McIntosh, Bryce, Crown, Phase Linear, Carver, BGW, JBL, Klipshe, Magnepan, Ampex, Luxman, Bang & Olufsen, Blaupunkt, etc. Heck, even my 600w Heath-kit power amp spanks Pioneer's largest power amp in numerous ways, and by a mile too!
Sony, Sherwood, Pioneer, Technics, Onkyo, Sansui, Denon (newer), Marantz (newer), Kenwood are just a few brands that shouldn't be sharing the shelving in hi-fi showrooms that carry the above mentioned quality brands. It's like parking a Mercedez next to a Kia. Throughout the years, I've either owned or repaired one or more of all the brands I mention above so I'm aware of the quality and sonic differences between various brands and models. To listen to an SAE preamplifier, SAE power amp, a Revox CD player, through a set of JBL Studio Masters or Klipshorns is practically breathtaking.
