Question:
Someone once told me that Yamaha amplifiers are superior to Pioneer or Kenwood amps because the Yamaha amp's use more current to produce the same amount of sound intensity as compared to a Pioneer or Kenwood amp design. According to him, 60 watts from a Yamaha receiver equals (or sounds the same as) approx. 100W from a similar Pioneer or Kenwood system. The receiver systems which I'm refering to are in the $300 - $400 price range. Does anyone have any tech. explanition as to why this may or may not be true. Is a Yamaha watt superior to a Pioneer watt?
Answer:
The amplifiers are rated with watts (you know that), and pioneer and yamaha's watt is the usual watt, you know I*U=W, or I^2*R=w, U^2/R=W... It's all the same, if you talking about watts, but the way that some company rated they amplifier is different (or it may be the same) depending is it a peak power, average (RMS based), famous PMPO.... It is not that i don't like yamaha products, i prefer yamaha mutch more then pioneer, because they tell you how is amplifier power supply made i.e. what kind of transformer is used, how strong (VA), and what is the capacity of filter capacitors which value impressed me in some yamaha amplifiers, because i made some amp's my self and i put some big value capacitances in my amps(8*37000 uF 95V) in two of my amps and it is a some kind of battery from witch your amp can draw very high current in a short period of time, but to short this one, it is a direct and very big improvement on sound fidelity.
