Yamaha is not clinical, I might say. Pioneer SA series is clinical, up front bass and clinical highs. But not Yamaha, Yamaha is bass up front, dynamic sounding amp, when it has to - there is punch, but also when it has to be mild - it's mild and it doesn't tire my ears. Kenwood, at least the one I had , was flat sounding amp with bass way beeehind but when you switched the loudness on it was loooot's and loot's of sloppy but powerful bass and quite really nice highs - the best highs I've heard... I'd say I prefer Yamaha Natural Sound. But I'm quite curious of Sansui amps - heard so much awesome stuff about them: that they are combination of both Pioneer and Yamaha amplifiers and take what's best from both of them... And that's kind of... Interesting? I would love to own Sansui amp as my backup or second amp just to see what's all the hype about. But they are expensive in Poland... And when I say expensive like, really expensive. I'm jealous of you guys when you get so much stuff from flea markets and so on or garage sales and in Poland they ask for something old as much money as for let's say Yamaha A-S701 "because it's vintage" and mostly it's just a "starting point" and the price ends up twice as high. Also I'm so in love with Yamaha CA series - but man, they are so expensive that you can choose from newest models of A-S series here in Poland - and it's INSANE. I remember times when you could get that stuff for a booze! Yes! A booze, here in Poland... And it's either domestic stuff or let's say some Marantz or Yamaha stuff. Now it's let's say a big MEH. A business because "it's vintage, man".
